Different levels of 5alpha-reductase type I and II, aromatase, and androgen receptor in hair follicles of women and men with androgenetic alopecia.
Findings revealed that both women and men have higher levels of receptors and 5alpha-reductase type I and II in frontal hair follices than in occipital follicles, whereasHigher levels of aromatase were found in their occipITAL follicles. Expand
Androgen Receptor Polymorphisms (CAG Repeat Lengths) in Androgenetic Alopecia, Hirsutism, and Acne
The data suggest that CAG-repeat length in AR may affect androgen mediated gene expression in hair follicles and sebaceous glands in men and women with these androgenic skin disorders. Expand
Although the definition of idiopathic hirsutism has been an evolving process, the diagnosis of IH should be applied only to hirsute patients with normal ovulatory function and circulating androgen levels, and patients respond to antiandrogen or 5alpha-RA inhibitor therapy. Expand
Androgenetic alopecia. New approved and unapproved treatments.
The new approved and the large multitude of unapproved treatments that are used to treat hair loss are covered. Expand
Immunohistochemical distribution of aromatase and 3B‐hydroxysteroid dehydrogenase in human hair follicle and sebaceous gland
It is hypothesized that AR may be one of many enzymes or factors that play a role in the HF cycle by regulating the level of androgens formed locally, whereas 3B‐HSD is localized in SG, converting weak androgen precursors to potent androgens, stimulating lipogenesis. Expand
Androgenetic Alopecia: Overview
- M. Sawaya
- Journal of cutaneous medicine and surgery
- 1 November 1999
Research in the last few years has shown that on the scalp there are local differences in the amounts of steroid metabolizing enzymes that convert weak androgens to more potent androgens, which is an important concept since the skin is an endocrine target tissue for androgen hormone action. Expand
Purification of androgen receptors in human sebocytes and hair.

Human sebaceous glands (SG) and hair follicles (HF) are target structures in the skin for androgen action. They contain steroid enzymes, capable of transforming weak androgens into the… Expand
Novel agents for the treatment of alopecia.
- M. Sawaya
- Seminars in cutaneous medicine and surgery
- 1 December 1998
A variety of new agents are emerging in the patient application process to gain protection and approval specifically for various forms of alopecia, as well as those in the over-the-counter (OTC) "natural" treatments category. Expand
