Background and objectivesMicrosurgical autologous hair transplantation, when performed as follicular unit transplantation, may permanently and naturally improve advanced androgenetic alopecia in men and women and also non-active scarring alopecias.Materials, methods and resultsSufficient donor hair and realistic patient expectations as well as an i...

The progressive nature of androgenetic alopecia requires an early and permanent hair-preserving treatment. This is particularly important when a hair transplantation is carried out in early stages or in young patients. In this combination, sustainable improvements can be achieved. With a systematic treatment with proven hair medications, particular...

Androgenetic alopecia is the most common hair loss disorder, affecting both men and women. Initial signs of androgenetic alopecia usually develop during teenage years leading to progressive hair loss with a pattern distribution. Moreover, its frequency increases with age and affects up to 80% Caucasian men and 42% of women. Patients afflicted with...

Hair follicle cells have a high turnover. A caloric deprivation or deficiency of several components, such as proteins, minerals, essential fatty acids, and vitamins, caused by inborn errors or reduced uptake, can lead to structural abnormalities, pigmentation changes, or hair loss, although exact data are often lacking. The diagnosis is established...

Moreover, its frequency increases with age and affects up to 80 % Caucasian men and 42 % of women. Patients diagnosed wit...

Alopecia areata (AA) is a nonscarring hair loss disorder with a 2% lifetime risk. Most patients are below 30 years old. Clinical types include patchy AA, AA reticularis, diffuse AA, AA ophiasis, AA sisiapho, and perinevoid AA. Besides scalp and body hair, the eyebrows, eyelashes, and nails can be affected. The disorder may be circumscribed, total (...

Androgenetic alopecia (AGA) is the most common hair loss disorder, affecting both men and women. Due to the frequency and the often significant impairment of life perceived by the affected patients, competent advice, diagnosis and treatment is particularly important. As evidence-based guidelines on hair disorders are rare, a European consensus grou...

Hair transplantation is a permanent treatment option for androgenetic alopecia in suitable male and female patients. The best long-term outcome is achieved in medically or spontaneously stabilized hair loss. In these cases, the redistributed hair increases density and scalp coverage. Realistic expectations, a good donor-to-recipient area ratio, car...

Hair Transplantation is a fully illustrated reference book that provides a state-of-the-art overview to all aspects of hair transplantation. Using a combination of written text, color photographs, and tables, eleven leading physicians and practitioners in the field discuss the latest surgical procedures to restore a natural-looking frame of hair to...

Acrodermatitis chronica atrophicans (ACA) represents the persistent late stage of borreliosis in which Borrelia species may survive for decades. Occasionally, B-cell lymphoma may develop in these patients, and additional neoplastic complications such as basal cell carcinoma or squamous cell carcinoma (SCC) have been reported once each over the past...

Various nonfollicular scalp conditions can cause secondary scarring or permanent alopecia. Possible causes are congenital defects, trauma, inflammatory conditions, infections, and neoplasms (rarely drugs). Associated signs and symptoms and other diagnostic procedures such as histopathology may aid in the diagnosis. Detection of the underlying disor...

Androgenetic alopecia (AGA), or male pattern hair loss, affects approximately 50% of the male population. AGA is an androgen-related condition in genetically predisposed individuals. There is no treatment to completely reverse AGA in advanced stages, but with medical treatment (eg, finasteride, minoxidil, or a combination of both), the progression...

Hair follicles produce hair fibers in a regular cycle. As part of their hair-producing role, hair follicles retain stem cells, promote cell growth and tissue invasion and induce angiogenesis. However, hair follicle function involves more than just hair fiber production. Hair follicles interact closely with the skin immune and neuroendocrine systems...

Although the complete picture for alopecia areata (AA) pathogenesis has yet to be determined, recent research has made much progress in our understanding of the disease mechanism. Numerous circumstantial evidence supports the notion that AA is fundamentally a disease mediated by inflammatory cells and may be autoimmune in nature. Recent research ha...

Alopecia areata (AA) is a hair loss disease marked by a focal inflammatory infiltrate of dystrophic anagen stage hair follicles by CD4+ and CD8+ lymphocytes. Although AA is thought to be an autoimmune disorder, definitive proof is lacking. Moreover, characterization of the primary pathogenic mechanisms by which hair loss is induced in AA is limited...
