,
July 2016 in “Biomedicine & Pharmacotherapy” In this animal study, researchers found that cedrol, a constituent from Platycladus orientalis, significantly promoted hair growth in a dose-dependent manner in female C57BL/6 mice, surpassing results from blank control and 2% minoxidil groups over 21 days.
22 citations
,
December 2014 in “Naunyn-Schmiedeberg's Archives of Pharmacology” This study found that baicalin activates Wnt/ß-catenin signaling in human dermal papilla cells, increasing alkaline phosphatase expression, growth factor expression, and promoting hair growth in mice.
11 citations
,
September 2014 in “International Journal of Molecular Sciences” This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.
27 citations
,
February 2014 in “Planta Medica” This study found that Scutellaria baicalensis extract and its main component baicalin inhibited androgen activation signaling and promoted proliferation of human dermal papilla cells, suggesting potential use in treating androgen-associated disorders.

,
April 2012 in “The New England Journal of Medicine” Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.
190 citations
,
October 2002 in “The FASEB journal” In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.
520 citations
,
February 2001 in “Journal of Clinical Investigation” This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.
