October 2002 in “The FASEB journal” Androgens may cause hair loss by increasing TGF-beta1 from scalp cells, which inhibits hair cell growth.
58 citations,
January 2006 in “Skin Pharmacology and Physiology” High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.
1 citations,
May 2017 in “InTech eBooks” Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
157 citations,

41 citations,
June 2006 in “Journal of Investigative Dermatology” Beard and scalp hair cells have different gene expressions, which may affect beard growth characteristics.
8 citations,
November 2020 in “Frontiers in Cell and Developmental Biology” Certain genes are more active in baby scalp cells and can help grow hair when added to adult mouse skin cells.
51 citations,
November 1998 in “The journal of investigative dermatology/Journal of investigative dermatology” Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.
19 citations,
October 1996 in “Dermatologic Clinics” Dermal papilla cells are key for hair growth and could help us understand and treat hair loss.

1 citations,
October 2021 in “Clinical, Cosmetic and Investigational Dermatology” Vitamin B3 may help prevent hair loss and promote hair growth by protecting scalp cells from stress and reducing hair growth-blocking proteins.

66 citations,
January 2000 in “Hormone Research in Paediatrics” Androgens can both promote and prevent hair growth due to differences in gene expression in hair follicles.
12 citations,
