May 2004 in “Journal der Deutschen Dermatologischen Gesellschaft” This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.
49 citations
,
March 2004 in “Journal of Investigative Dermatology” This study found that the hHa7 gene in hair follicle trichocytes is the first identified to have its expression directly regulated by androgens, suggesting it as a marker for androgen action on hair follicles.

January 2004 in “Journal of Investigative Dermatology” 191 citations
,
December 2003 in “Journal of Investigative Dermatology” Male pattern baldness is largely genetic, linked to the androgen receptor gene, and may relate to certain health issues.
78 citations
,
October 2003 in “Cochrane library” This review found that adding cyproterone acetate to estradiol showed a subjective improvement in hirsutism versus placebo, but comparisons with other therapies revealed no clinical differences.
215 citations
,
September 2003 in “Journal of Biological Chemistry” This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.
139 citations
,
June 2003 in “Journal of Investigative Dermatology Symposium Proceedings” This article reviews androgenetic alopecia in women, highlighting diagnosis criteria and noting that topical minoxidil is currently the only proven treatment for hair growth; it reports no clinical trial findings.
289 citations
,
May 2003 in “Journal of Investigative Dermatology” This study demonstrates that human skin is capable of steroid hormone synthesis, but its role in androgenic skin disorders like acne and alopecia is yet to be clarified.
52 citations
,
May 2003 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.
91 citations
,
May 2003 in “American Journal of Pathology” This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.
51 citations
,
January 2003 in “Hormone Research in Paediatrics” This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.
233 citations
,
November 2002 in “The journal of investigative dermatology/Journal of investigative dermatology” This review explores androgen metabolism in the skin, highlighting enzyme localization and potential implications for treating androgen-dependent skin conditions, but it reports no new clinical results.
149 citations
,
June 2002 in “British Journal of Dermatology” Minoxidil works better for female hair loss, but cyproterone reduces scalp oiliness and causes menstrual issues.
226 citations
,
September 2001 in “Journal of The American Academy of Dermatology” Hair loss in women is genetic, diagnosed by examination and biopsy, and treated with minoxidil, finasteride, or transplantation.
176 citations
,
August 2000 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism” In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.
70 citations
,
January 2000 in “Hormone Research in Paediatrics” This article reviews the characteristics and classification of SAHA syndrome and its relationship with other conditions, without presenting new clinical findings.
82 citations
,
January 2000 in “Hormone Research in Paediatrics” This study describes the enzymatic processes through which DHEA is converted to active sex steroids in human skin, highlighting an androgenic effect on sebaceous glands and estrogenic effects in the vagina.
63 citations
,
November 1999 in “British journal of dermatology/British journal of dermatology, Supplement” This study observes the expression of mRNA for androgen receptor, 5α‐reductase, and 17β‐hydroxysteroid dehydrogenase in human dermal papilla cells.
173 citations
,
July 1995 in “Biochemical and biophysical research communications” This study suggests that IGF-I may mediate androgen-induced hair growth in outer root sheath cells cocultured with beard dermal papilla cells.
124 citations
,
August 1994 in “Journal of Investigative Dermatology” This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.
29 citations
,
May 1986 in “Journal of Steroid Biochemistry” Androgens don't directly affect hair cell growth or protein production.
