Androgens and alopecia

Molecular and Cellular Endocrinology, 2002
Androgens have profound effects on scalp and body hair in humans. Scalp hair grows constitutively in the absence of androgens, while body hair growth is dependent on the action of androgens. Androgenetic alopecia, referred to as male pattern hair loss (MPHL) in men and female pattern hair loss (FPHL) in women, is due to the progressive miniaturization ...

Distinguishing immunohistochemical features of alopecia areata from androgenic alopecia

Journal of Cosmetic Dermatology, 2018
SummaryBackgroundDistinction between alopecia areata (AA) and androgenic alopecia (AGA) can be made according to clinical presentation and biopsy findings. However, it is sometimes difficult to differentiate them, especially when the diffuse pattern of both AA and AGA is in the differential diagnosis of hair loss in androgen‐dependent areas ...

Medical treatment of male pattern alopecia (androgenic alopecia)

Head & Neck Surgery, 1985
AbstractThe causes and potential causes of androgenic alopecia in men and women are discussed. The scientific attempts at reversing this process are detailed including use of estrogen, thyroid, progesterone, and minoxidil. At present, the practical approach for the clinician is to ascertain in females that an androgen overproduction syndrome is not ...

The Transverse Anatomy of Androgenic Alopecia

The Journal of Dermatologic Surgery and Oncology, 1990
Abstract. Twenty‐five biopsy specimens from the balding frontal scalp of five patients were studied. Processing included vertical and transverse (horizontal) sectioning, to‐luidine blue and hematoxylin and eosin staining, and fixed and frozen sectioning. Findings included decreased hair density, increased numbers of vellus hairs, and alteration of the

Estrogen and Progesterone Receptors in Androgenic Alopecia Versus Alopecia Areata

The American Journal of Dermatopathology, 1998
In some situations, hair growth is under hormonal control. Androgenic alopecia is characterized as hormonally driven hair loss in the genetically susceptible individual. During pregnancy, hair growth is increased, as estrogen appears to prolong the anagen phase.

Expression of androgen receptor coactivator ARA70/ELE1 in androgenic alopecia

Journal of Cutaneous Pathology, 2005
Background:  Androgens have been implicated in androgenic alopecia as evidenced by the increased cutaneous expression of androgen receptor (AR), 5α‐reductase, and decreased aromatase. Abnormalities of the AR‐signal transduction pathway probably participate in the development of androgenic alopecia. ARA70/ELE1 is an AR coactivator with two isoforms, one

Alopecia due to high androgen index contraceptives

JAAPA, 2018
ABSTRACT Adverse reactions to hormonal contraceptives are a common patient concern. Alopecia, an adverse reaction to androgen activity caused by the progestin component of hormonal contraceptives, can cause considerable psychosocial distress for women. This article discusses how to identify the level of androgen activity in certain progestins,
