,
July 2007 in “Journal of Investigative Dermatology” The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.
58 citations
,
January 2006 in “Skin Pharmacology and Physiology” This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.
