    TLDR Apigenin may help promote hair growth and could treat hair loss.
    In the 2009 study, researchers developed a cell-based assay to evaluate the effects of substances on TGF-ß1 promoter activity, which is linked to hair growth suppression in androgenetic alopecia. They found that dihydrotestosterone (DHT) increased TGF-ß1 promoter activity, while curcumin decreased it. The study highlighted that apigenin, a compound known for its antioxidant and anti-inflammatory properties, reduced TGF-ß1 expression and stimulated the proliferation of human dermal papilla cells and keratinocytes, as well as hair follicle elongation in rat vibrissa hair follicle cultures. Apigenin at concentrations of 1 and 5 µM significantly increased cell proliferation and hair shaft growth, with 5 µM being more effective than 10 µM. These findings suggest that apigenin has the potential to promote hair growth and could be a therapeutic option for treating androgenetic alopecia. The study did not specify the number of samples or participants involved.
