Severe Hair Loss of the Scalp due to a Hair Dye Containing Para phenylenediamine

Authors:

Abstract and Figures

We report the case of a 41-year-old female showing severe hair loss approximately 90% after the use of a hair dye. These symptoms developed six days after the use of a hair dye containing PPD. A patch test showed a (++) reaction at 48 h to 1% PPD in petrolatum, whereas all metals and white petrolatum were negative. She was therefore diagnosed with contact dermatitis due to PPD, resulting in hair loss. The skin lesions gradually improved after starting treatment with the systemic corticosteroids. The possibility that allergic contact dermatitis from hair dyes may be responsible for telogen effluvium should always be considered in a patient with increased hair loss.

We report the case of a 41-year-old female showingsevere hair loss approximately 90% after the use of a hair dye. These symptoms
developed six days after the use of a hair dye containing PPD. A patch test showed a (++) reaction at 48 h to 1% PPD in petrolatum,
whereas all metals and white petrolatum were negative. She was therefore diagnosed with contact dermatitis due to PPD, resulting
in hair loss. The skin lesions gradually improved after starting treatment with the systemic corticosteroids. The possibility that
allergic contact dermatitis from hair dyes may be responsible for telogen euvium should always be considered in a patient with
increased hair loss.
1. Case Report
A 41-year-old female was referred because of edema on the
face and hair loss with severe itching of the scalp. The itching
of the scalp started 1 day after the use of a hair dye containing
PPD, and hair loss symptoms developed 6 days after the
use of the hair dye (Figure 1(a)). Hair loss had spread to
approximately 90% of the scalp 4 months later (Figure 1(b)).
Detailed anamneses revealed that the patient had started
to use hair dye 5 years prior to the current presentation
and had developed sprier itching of the scalp 1 to 2 days
after her hair was dyed at a hair dresser’s several months
ago . All parameters examined during a blood test were
within the normal limits. There was no history of associated
dermatitis. A patch test showed a (++) reaction at 48 h and
72 h to 1% PPD in petrolatum. She was therefore diagnosed
with contact dermatitis due to PPD, resulting in hair loss.
The skin lesions gradually improved after starting treatment
with the systemic corticosteroids. The patient has not had a
recurrence for 18 months since she stopped using the hair
dye in question.
2. Discussion
Several cases of severe facial and scalp dermatitis have been
reported following the use of permanent hair dyes, and
these dyes often contain paraphenylendiamine (PPD). PPD is
known to be the most frequent contact allergen found in hair
dyes [1]. The possibility that allergic contact dermatitis from
hair dyes may be responsible for telogen euvium should
always be considered in a patient with increased hair loss [2].
This report presents the case of a patient who experienced
severe hair loss after the use of a hair dye containing PPD.
We concluded that the explanation for the severe hair loss in
our case was a concurrent sensitization and allergic reaction
to PPD, as the product had been applied repeatedly over a
long period of time.
Hair dye reactions are usually diagnosed by the patients
themselves, and epidermological studies found a range
between 0.1% and 1% of the patients sensitized to PPD [3,4].
The most frequent symptoms tend to be erythema of the
face, scalp, and ears following the use of permanent hair dyes
containing PPD. Severe facial and scalp dermatitis with PPD
has been reported in several cases, with symptoms of edema,
suppuration, and ulceration of the face, scalp and eyelids
[5]. The reports of hair loss in the scalp due to hair dyes
containing PPD is rare, and there have been only 2 reported
cases of hair loss in the scalp due to a PPD allergy associated
with dermatitis in a consumer-based study [5]. Wachsmuth
and Wilkison reported a case of eyelash loss due to an allergic
reaction to PPD in mascara [6].

Figure 1: (a) A female with an allergic reaction to hair dye with severe hair loss on the scalp. This picture was taken 6 days after she had
colored her hair. (b) The hair loss spread to approximately 90% of the scalp 2 months later. Partial white hair regrowth was also observed.
Sosted et al. reported that many cases of PPD allergy go
unreported, probably because the patient is able to make
the connection between the reaction and the hair dye and
therefore does not seek medical advice. Our case had a severe
face edematous reaction, with approximately 90% hair loss
that required treatment with systemic corticosteroids.
3. Conclusions
Many cases of dermatitis due to hair dye may be overlooked,
but severe dermatitis may sometimes last for more than
3 weeks [5]. Therefore, dermatologists need to pay more
attention to hair dye allergies.

... Due to the destructive nature of permanent dye products, the hair fibre structure suffers cumulative damages that lead to split ends and dry and dull hair [4]. More important, those products have been identified as the source of various adverse health effects, such as chemical and allergic reactions that many times result in acute or mild dermatitis with consequent hair loss [2,[5][6][7][8]. Even more alarming is the fact that some studies have raised the possibility that the long-term usage of permanent dyes can cause serious and systemic side-effects, such as the increased risk of developing certain cancers [9-13]. ...
... The proteolytic processing of POMC by PC1 produces the peptides adrenocorticotropin (ACTH) and β-Lipotropin (β-LPH), with the latter being further processed to β-endorphin (β-END) and β-melanocyte-stimulating hormone (β-MSH). PC2 cleaves the first 14 amino acids of the ACTH sequence to generate ACTH (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)OH, the precursor of α-MSH [280][281][282]. POMC-derived products are the main regulators of follicular melanogenesis, and even unprocessed POMC was reported to stimulate melanin production ( Figure 8). ...

The natural colour of hair shafts is formed at the bulb of hair follicles, and it is coupled to the hair growth cycle. Three critical processes must happen for efficient pigmentation: (1) melanosome biogenesis in neural crest-derived melanocytes, (2) the biochemical synthesis of melanins (melanogenesis) inside melanosomes, and (3) the transfer of melanin granules to surrounding pre-cortical keratinocytes for their incorporation into nascent hair fibres. All these steps are under complex genetic control. The array of natural hair colour shades are ascribed to polymorphisms in several pigmentary genes. A myriad of factors acting via autocrine, paracrine, and endocrine mechanisms also contributes for hair colour diversity. Given the enormous social and cosmetic importance attributed to hair colour, hair dyeing is today a common practice. Nonetheless, the adverse effects of the long-term usage of such cosmetic procedures demand the development of new methods for colour change. In this context, case reports of hair lightening, darkening and repigmentation as a side-effect of the therapeutic usage of many drugs substantiate the possibility to tune hair colour by interfering with the biology of follicular pigmentary units. By scrutinizing mammalian pigmentation, this review pinpoints key targetable processes for the development of innovative cosmetics that can safely change the hair colour from the inside out.
... H 2 O 2 , monoethanolamine, and PPD in hair dyes have been proposed as the main causative ingredients of hair dyeing-induced hair loss. 64,65 Based on histological examination conducted in animal tests, oxidative stress may be the mechanism underlying hair-dye induced dermatitis. 64,65 H 2 O 2 and monoethanolamine, in particular, were shown to synergistically induce oxidative stress and cytotoxicity in human keratinocytes, an observation that is consistent with the histological data. ...

Given the worldwide popularity of hair dyeing, there is an urgent need to understand the toxicities and risks associated with exposure to chemicals found in hair dye formulations. Hair dyes are categorized as oxidative and nonoxidative in terms of their chemical composition and ingredients. For several decades, the expert panel's Cosmetic Ingredient Review (CIR) has assessed the safety of many of the chemicals used in hair dyes; however, a comprehensive review of hair dye ingredients and the risk of exposure to hair dyeing has not been documented. Herein, we review the safety of the various chemicals in oxidative and nonoxidative hair dyes, toxicities associated with hair dyeing, and the carcinogenic risks related to hair dyeing. While many compounds are considered safe for users at the concentrations in hair dyes, there are conflicting data about a large number of hair dye formulations. The CIR expert panel has ratified a number of coloring ingredients for hair dyes and banned a series of chemicals as carcinogenic to animals and unsafe for this application. The use of these chemicals as raw materials for producing hair dyes may result in the synthesis of other contaminants with potential toxicities and increased risk of carcinogenesis. It is an open question whether personal or occupational hair dyeing increases the risk of cancer; however, in specific subpopulations, a positive association between hair dye use and cancer occurrence has been reported. To address this question, a better understanding of the chemical and mechanistic basis of the reported toxicities of hair dye mixtures and individual hair dye ingredients is needed. It is anticipated that in-depth chemical and systems toxicology studies harnessing modern and emerging techniques can shed light on this public health concern in the future.
... Hair loss can also be inherited, also called androgen-related hair loss or baldness, which usually occurs between 30 and 40 years of age, more men than women. Recent studies by scientists show that the climate of the seasons also significantly affects hair loss [6]. Hair loss may be a normal sign, but at the same time, the symptom of a variety of serious pathology. ...
... It is functional food, hair growth pills, topical medicines, most of the items in Western medicine are imported. It is possible to include common products for hair loss such as minoxidil, spironolactone, finasteride, etc [6]. These products have the effect of supplementing vitamins, hair nourishing minerals, thereby stimulating hair growth, improving hair follicles and scalp. ...

Finding out methods or ways to improve people's health is always focused. How to have beautiful hair is what both men and women want. In order to achieve that, people used natural ingredients to nourish their hair in addition to modern Western medical therapies. The paper was based on sources of journals, documents as well as the survey results completed by patients and foreigners living in Ho Chi Minh city, Vietnam. The research paper once again determines the importance of folk therapies as well as some great herbs in this country.
... Currently, the concern with hair colour as well as length, shape, and density is higher than ever, as society focuses more and more on beauty and youthfulness. Hair colouring, permanent waving, or straightening rely on aggressive chemical and/or physical processes that can result in acute or chronic deleterious traumas, such as hair loss or even cancer development [14][15][16][17][18][19][20][21][22][23]. Moreover, these procedures cause split, dry, and dull hair due to cumulative damage to the fibre structure [24,25]. ...

Hair dyeing is a popular practice dating back to ancient Egyptian times. Initially, hair dye use was restricted to concealing grey and white hairs of the elderly population. However, in recent times, its use is common among the younger generation as a fashion statement. Hair dye contact dermatitis is a common dermatological condition encountered by dermatologists. It is a delayed type of hypersensitivity reaction that commonly affects the scalp and the vicinity of hair line and neck. Para-phenylenediamine (PPD), a synthetic aromatic amine is the most common allergen specifically implicated in hair dye contact dermatitis. Para-phenylenediamine was announced as the allergen of the year in 2006 by the American Contact Dermatitis Society. Contact allergy to para-phenylenediamine can occur in 0.1–2.3% of the general population. Epicutaneous patch testing is the gold standard test for the diagnosis of hair dye contact dermatitis. However, para-phenylenediamine carries a risk of cross-sensitivity and co-sensitization to other allergens. Apart from contact dermatitis, hair dye use is also associated with various other cutaneous adverse effects such as pigmentary changes, hair loss, skin malignancies and autoimmune disorders. Due to the various adverse effects associated with hair dye use, it is prudent to look for safer alternatives to allergenic hair dyes. In this article, we review the epidemiology, cutaneous and systemic adverse effects associated with hair dye use, patch testing, preventive strategies to minimize the risk of hair dye contact dermatitis, and treatment aspects.
... The possibility that allergic contact dermatitis from hair dyes may be the reason for the hair loss among the consumers. 27 Also, factors such as natural aging process, seasonal variations, imbalances in vitamins and minerals, endocrine disorders, genetic mutations, immune-related diseases, bacterial or fungal infections of the scalp, parasite infestations, atopic dermatitis, and psychological problems such as stress also be considered as a possible cause of hair loss among the study population, which may contribute along with the use of hair dye for hair loss. 28 Unlike our study, a study from the Netherlands found less adverse events with the use of hair care products (29.5%) and the rest of the events reported were due to product used for skin. ...

Background Cosmetovigilance is a term used for the activities related to the collection, evaluation, and monitoring of reporting of undesirable events observed during or after normal or reasonably foreseeable use of a cosmetic product. Aim The study was conducted to assess the adverse cosmetic events from a tertiary care hospital. Patients/Methods The patients visiting the study site was reviewed and those who met the study criteria are enrolled in the study after administration of the informed consent. Study participants were followed on regular intervals either telephonically or hospital visits in order to determine the outcome. The causality assessment of the reported event was performed using Colipa and PLM method. Results During the study period 22,893 patients visited the dermatology department, in which 87 subjects were enrolled in the study. The incidence of adverse cosmetic event was 0.38%. Hair care products caused more events than body care products. In 73.56% of cases, the suspected cosmetic was withdrawn and all the study population received symptomatic treatment for the adverse events. Causality assessment of Using Colipa method, categorized 49.43% events as likely and using PLM method, 64.37% events were probable. Study couldn't identify any predictors of adverse cosmetic events. Median cost associated with the management of ACRs for hair care products and body care products were 716.62 (IQR: 1011.36–470) and 557.4 (IQR: 711.63–373.8). Conclusion The study suggest need for approaches such as awareness programs among the cosmetic sellers, consumers and other stakeholders on cosmetovigilance needs to be developed and implemented.

Background Scalp conditions are often multifactorial. Objective To characterize patients with scalp involvement and patch testing outcomes. Methods Retrospective cross-sectional analysis of North American Contact Dermatitis Group data (1996-2016). Study groups included patients with scalp involvement (<3 anatomic sites coded) with or without additional sites. Results 4.8% (2,331/48,753) had scalp identified as one of up to three affected anatomic sites. Roughly one-third of “scalp-only” individuals had a specific primary diagnosis of allergic contact dermatitis (ACD) (38.6%), followed by seborrheic dermatitis (17.2%) and irritant contact dermatitis (9.3%). When adjacent anatomical sites were affected, ACD was more frequently identified as the primary diagnosis (>50%). The top 5 currently clinically relevant allergens in scalp-only patients were p-phenylenediamine, fragrance mix I, nickel sulfate, balsam of Peru, and cinnamic aldehyde. Methylisothiazolinone sensitivity was notable when adjacent anatomical sites were involved. Top 3 specifically identified sources for scalp-only allergens were hair dyes, shampoo/conditioners, and consumer items (e.g. hair appliances, glasses). Limitations Tertiary referral population. Conclusion Isolated scalp involvement was less likely to be associated with ACD than when adjacent anatomical sites were involved. Overlap with multiple diagnoses was frequent including seborrheic dermatitis, irritant dermatitis, and/or other dermatoses. P-phenylenediamine was the most common allergen.

Fast and facile coating strategies play a key role in the surface engineering and functionalization of materials for various applications. Herein, we report a safe, rapid, and eco-friendly hair dyeing process for natural gray hair via the optimized formation of metal‒phenolic networks (MPNs). MPNs composed of gallic acid display high performance and the coloration is tunable by varying the metal ion types. MPN-based hair dyeing is tolerant to repeated washing (at least 50 times) with detergent solution without color fading and can be discolored in acidic solution (pH < 2). The mechanism of self-assembled MPNs for hair dyeing is investigated by Raman and UV–vis absorption spectroscopy. Cell studies in vitro and skin toxicity tests in vivo demonstrate the superiority (i.e., biocompatibility and hair regrowth) of MPNs for hair dyeing compared to p-phenylenediamine. The reported strategy for hair dyeing avoids the use of toxic substances present in common hair dyes and has negligible damage to the hair structures and tensile strength.

Importance: Consumers have reported skin rash/irritation and hair loss/breakage with Wen by Chaz Dean Sweet Almond Mint Cleansing Conditioner (WCDSAMCC), however epidemiologic, toxicologic and clinical hair loss studies have not provided an explanation. Contact dermatitis has been hypothesized. Objective: To assess the tolerability of six products: WCDSAMCC, three other hair cleansing conditioners, and two controls [salicylic acid shampoo (SAS) and baby shampoo (BS)]. Design: Double-blind, randomized, controlled trial. Setting: Single-site study. Population: General population volunteers. Intervention: Standard semi-open patch tests (SOPTs) and duration-escalation repeat open application tests (ROATs) over 5 weeks. Main Outcome Measures: Primary outcome measure was “stopping point” [ROAT total component score ≥6 (maximum 10) or global ≥4 (maximum 5)]. Secondary outcomes included “any reaction” (ROAT component score ≥1) and SOPT ≥ doubtful. Results: Two hundred of 298 volunteers were enrolled. There were no significant differences in the tolerability of WCDSAMCC and any of the other three hair cleansing conditioners as assessed by SOPT or ROAT. WCDSAMCC was significantly better tolerated than SAS (“stopping point”, or “any reaction”, p values<0.0001) as well as BS (p = 0.01). The frequency of doubtful SOPT reactions was lowest for WCD (2.2%) and highest for SAS (7.1%, p = 0.04). Conclusions: As assessed by both ROAT and SOPTs, WCDSAMCC was similar in tolerability to three other hair cleansing conditioners and significantly better tolerated than both controls (SAS and BS). Summary: This double-blind, randomized, controlled study found that WCDSAMCC was similar in tolerability to three other HCCs and was significantly better tolerated than both SAS and BS. This study provides critical clinical evidence on the comparative lack of cutaneous effects with use of WCDSAMCC. Trial Registration: NCT03483025 ClinicalTrials.gov.

In 1990 and 1998 15-41-year-old people were patch-tested in 2 cross-sectional studies of random samples of the population in the western part of Copenhagen County, Denmark. In 1990, 290 subjects and in 1998, 469 subjects were patch-tested. The participation rates were 69% and 51%, respectively. Contact sensitivity to one or more haptens was found in 15.9% and 18.6% in 1990 and 1998, respectively. Nickel sensitivity is still the most common contact sensitivity. The risk of contact sensitivity to the cosmetic-related haptens included in the series (formaldehyde was not included) increased significantly from 2.4% in 1990 to 5.8% in 1998 (odds ratio 2.44, 95% confidence interval 1.04-5.73). The prevalence of contact sensitivity to cosmetic-related allergens has been doubled between 1990 and 1998.

After observing 2 cases of acute telogen effluvium induced by allergic contact dermatitis to hair dyes, we decided to evaluate the effects of acute contact dermatitis of the scalp on the hair cycle. Single-center, 6-month study of consecutive patients affected by acute scalp dermatitis. Department of Dermatology, University of Bologna, Bologna, Italy. Diagnosis of allergic contact dermatitis of the scalp was confirmed by patch testing. Eight women presenting with acute contact dermatitis of the scalp entered the study. Hair shedding was evaluated monthly for 6 months by pull test and wash test. Increased hair loss was detected in 4 of the 7 patients who completed the study. Hair loss was mild to moderate and appeared 2 to 4 months after the episode of scalp dermatitis. A scalp biopsy specimen from 2 patients confirmed the diagnosis of telogen effluvium. Allergic contact dermatitis of the scalp should be included among the possible causes of telogen effluvium. The pathogenesis of telogen effluvium caused by contact dermatitis is unknown but may be related to cytokine release during the inflammatory process.

We aimed to determine the prevalence of contact sensitization in the general population and to investigate associations with important sociodemographic and medical characteristics. Within a population-based nested, case-control study in Germany, we performed patch tests with 25 standard allergens in 1141 adults (50.4% female, age median 50 years). Additional information was obtained by a dermatologic examination, a standardized interview, and blood analysis. At least one positive reaction was exhibited by 40.0% of the subjects, with reactions most frequently observed to fragrance mix (15.9%), nickel (13.1%), thimerosal (4.7%), and balsam of Peru (3.8%). Women were sensitized more often than men (50.2% vs 29.9%, OR 2.36, CI 1.84-3.03), and this was also significant for fragrance mix, nickel, turpentine, cobalt chloride, and thimerosal. Contact sensitization was more frequent in subjects who reported adverse skin reactions (53.8% vs. 32.6%; OR 2.41, CI 1.85-3.14), and this was particularly true for sensitization to nickel (45.5% vs 8.8%, OR 8.64, CI 5.67-13.17) and fragrance mix (29.0% vs 14.0%, OR 2.51, CI 1.60-3.91) and the corresponding intolerance of fashion jewelry and fragrances. Contact sensitization decreased with increasing degree of occupational training (unskilled 45.9%, apprenticeship 40.1%, technical college 40.4%, and school of engineering 12.5%; P=0.023; trend test P=0.042). Significant associations of contact sensitization and presence of allergen-specific IgE antibodies, atopic eczema, or psoriasis were not observed. Frequency estimates for the general adult population based on these findings were 28.0% for overall contact sensitization and 11.4% for fragrance mix, 9.9% for nickel, and 3.2% for thimerosal. It is concluded that contact allergy is influenced by sociodemographic parameters and plays an important role in the general population.

Severe facial and scalp dermatitis following the use of permanent hair dyes has been reported in several cases. Para-phenylenediamine (PPD) is known as a potent contact allergen, and PPD is allowed in hair dye at a concentration of 6%. Hair dye reactions are usually diagnosed by the patients themselves, and adverse reactions to hair dye may not necessarily be recorded by the health care system, unless the reactions are especially severe. Based on this assumption, we suspected that hair dye dermatitis was occurring more frequently than reported in the literature. Consumer complaint-based data were obtained by advertising for persons with adverse reactions to hair dye. Among those responding to the advertisement, 55 cases of severe, acute allergic contact dermatitis were identified. The main symptoms were severe oedema of the face, scalp and ears, and clinically this was often mistaken for angio-oedema. The 55 cases comprised a total of 75 visits to the health service and 5 admissions to hospital. 18 persons had sick leave, which supports the impression of very severe dermatitis reactions. 60% were treated with antihistamine, while 52% were treated with corticosteroids. 29% of the cases were patch tested and all were found positive to PPD. Our data presented here clearly show that PPD and its derivatives in hair dye at the present concentrations presents a significant health risk for the population. Furthermore, the severe acute allergic skin reactions are often misdiagnosed in the health care system. The frequency of allergic contact dermatitis resulting from hair dye is likely to be underestimated. New methods to survey the frequency of adverse reactions should be considered.
