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.
18 citations
,
April 2004 in “The journal of investigative dermatology/Journal of investigative dermatology” This review explores the potential genetic and epigenetic influences on hair whorl patterns and suggests that pattern formation may involve basic physical-chemical laws, although it reports no new experimental findings.
44 citations
,
March 2004 in “Journal of Investigative Dermatology” This study observed that in vitro treatment of male frontotemporal scalp hair follicles with 17-β-estradiol stimulated hair shaft generation and hair matrix keratinocyte proliferation, suggesting potential anagen-prolonging effects.
76 citations

January 2004 in “Journal of Investigative Dermatology”
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.
72 citations
,
November 2002 in “Journal of Investigative Dermatology” Estrogen receptor α controls hair growth cycles and skin thickness in male mice.
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.
41 citations
,
July 2001 in “PubMed” This study reported that while finasteride and progesterone significantly inhibited dihydrotestosterone synthesis in dermal papillae, estrogens were less effective.
71 citations
,
February 2000 in “Endocrinology and metabolism/American journal of physiology: endocrinology and metabolism” This study found that topical estradiol inhibits hair growth in mice by preventing the hair follicle's transition from resting to growth phase, a process reversible with an estrogen receptor antagonist.
32 citations
,
December 1999 in “Journal of Investigative Dermatology Symposium Proceedings” This study found that the effectiveness of 17-beta-estradiol in inhibiting hair growth depends on its application method, and noted significant sex differences in response to 17-alpha-estradiol in male and female mice.
1113 citations
,
August 1999 in “The New England Journal of Medicine” This article discusses the biologic and psychosocial significance of hair, the current limitations in hair growth drugs, and anticipates future therapies based on advancing hair follicle research.
53 citations
,
October 1998 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that cyclophosphamide induced significant keratinocyte apoptosis in anagen hair follicles of mice, while topical calcitriol-analogs reduced this apoptosis, suggesting a protective effect against chemotherapy-induced alopecia.
34 citations
,
September 1997 in “Acta Dermato Venereologica” This study found that RXR agonists stimulated human hair follicle growth and survival in vitro, suggesting potential for promoting hair growth in humans.
154 citations
,
October 1996 in “Proceedings of the National Academy of Sciences of the United States of America” This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.
48 citations
,
April 1995 in “PubMed” This study found that dermal papilla cells from beard and axillary hair follicles can produce androgen-dependent factors that stimulate proliferation in adjacent follicular epithelial cells under testosterone influence.
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.
36 citations
,
April 1994 in “PubMed” This study introduces a mouse model of cyclophosphamide-induced alopecia, which effectively replicates human chemotherapy-induced hair loss and can be pharmacologically manipulated to study hair regrowth patterns.
210 citations
,
July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology” This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.
77 citations
,
January 1993 in “Skin Pharmacology and Physiology” In this study, topically applied glucocorticosteroids were found to block hair growth at the stage of hair formation, but not the initiation of hair growth, in a mouse model.
22 citations

,
March 1942 in “Journal of Endocrinology” This article reviews studies on thyroid influence on hair growth, noting varied results, including accelerated growth in some normal and underfed rats after thyroid administration, but reports no clinical results.
