March 2015 in “Biomolecules & Therapeutics” In this study, BP201, derived from porcine lung phospholipids, promoted hair growth in mice, especially when combined with minoxidil, and increased hair follicle numbers and dermal papilla cell proliferation.
88 citations
,
February 2011 in “Journal of Dermatological Science” This study found that topical minoxidil modestly extended the anagen phase in mice by activating β-catenin activity in dermal papilla cells.
1 citations
,
April 2007 in “PubMed” Tacrolimus helps mice grow hair by activating hair follicles.
114 citations
,
January 2007 in “International Journal of Dermatology” This study found that caffeine can stimulate hair growth in vitro and counteract testosterone-induced growth suppression in hair follicles from male AGA patients.
1 citations
,
January 2004 in “Linchuang pifuke zazhi” This study found that while SP did not enhance linear hair growth in cultured hair follicles, it prolonged the anagen phase and altered the expression of growth factors and apoptosis-related molecules, suggesting a stimulatory effect on hair growth.
January 2003 in “Journal of Clinical Dermatology” In this study, TNF- inhibited hair growth in cultured human hair follicles, while minoxidil did not counteract this effect or stimulate growth.
15 citations
,
April 2001 in “Journal of Dermatological Science” This study found that KF19418 stimulated hair follicle growth in vitro and accelerated hair regrowth in a mouse alopecia model, with effects comparable to minoxidil.
April 2000 in “Chinese Journal of Dermatology” This study found that epidermal growth factor may stimulate the growth of hair follicle epithelium and potentially accelerate the transition from anagen to catagen phase in cultured human hair follicles.
23 citations
,
May 1998 in “Journal of Dermatological Science” This study suggests that skin sections from 4-week-old C3H mice could serve as an in vitro model for human androgenic alopecia, as minoxidil partially reverses suppressed hair follicle elongation.
September 1990 in “Journal of Dermatological Science” March 1990 in “Journal of Dermatological Science” 
121 citations
,
March 1989 in “Journal of Investigative Dermatology” Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.
8 citations
,
January 1989 in “PubMed” This study found that applying minoxidil topically had no recognizable effect on hair follicle growth in newborn mice, though it highlighted apoptosis as a potential marker for hair regression research.
