androgenetic alopecia is the most common form of hair loss in men. the present study was designed to evaluate the hair growth-promoting activity of a preparation of the adiantum capillus veneris linn. (a. capillus veneris linn.) on albino mice using a testosterone-induced alopecia model. five groups of albino mice were studied: (a) testosterone solution only (n=6); (b) testosterone ‏+ finasteri...

Hair loss is an uncommon manifestation of secondary syphilis. Its clinical manifestations include diffuse effluvium or patchy ‘moth-eaten’ pattern of alopecia. Although syphilitic alopecia is non-scarring hair loss often associated with other mucocutaneous lesions of secondary syphilis, it might well be the only presenting symptom of syphilis. Secondary syphilis was diagnosed in ten homosexual ...

BACKGROUND Diffuse alopecia areata or canities subita is a rare variant of alopecia in which hair loss is associated with regrowth of white hairs and possible lightening of the skin. Preferential loss of pigmented hair in this disorder may be related to the melanin pigment system and/or melanocytes. Acquired generalized anhidrosis can be associated with autoimmune disease, cancer, graft-vs-host...

Diffuse alopecia is mainly caused by telogen effluvium, diffuse androgenetic alopecia (female-pattern hair loss) and diffuse alopecia areata. Differential diagnosis between the three disorders may be difficult in several occasions. In this second part of our study, chronic telogen effluvium and diffuse alopecia areata are discussed in detail, including clinical, dermoscopic and histological asp...

Female androgenetic alopecia (FAGA) is a common and distressing cause of hair loss, caused by androgens in genetically susceptible women [1, 2], in which dihydrotestosterone (DHT) binds to androgen receptors leading to miniaturization of scalp hair follicles [3]. FAGA, characterized by a specific diffuse loss of hair of the parietal or frontovertical regions ('in the crown'), where 5α-reductase...

Hypothyroidism is a common and well recognized cause of diffuse hair loss. Zinc and other trace elements such as copper and selenium are required for the synthesis of thyroid hormones, and deficiency of these can result in hypothyroidism. Conversely, thyroid hormones are essential for the absorption of zinc, and hence hypothyroidism can result in acquired zinc deficiency. The hair loss attribut...

Introduction: Selective serotonin reuptake inhibitors (SSRIs) are widely advised as antidepressants. Association of SSRIs with hair loss is rare and limited to a few case reports. In this case study, two patients developed diffuse hair loss during sertraline treatment. Case Presentation: Mr. A was a 47-year-old married man with a diagnosis of panic disorder according to the DSM-V criteria and s...

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 (scalp hair loss), and universal (loss of all ha...

AIM In this study, we investigated the sensitivity of TrichoScan, a computer-based phototrichogram, in the evaluation of diffuse hair loss in women and the relationship between iron deficiency anemia and hair loss. MATERIALS AND METHODS We recruited 100 female patients with diffuse hair loss. In all of the patients, a 1-cm2 area of hair located in a temporoparietal region was shortened to 0.5...
