I'm reallly skeptical of herbal supplements for most things. I had been pursuing an all-of-the-above approach for hair loss for about a year including caffeine shampoo, occasional topical (not oral) finasteride/rapamycin combo, and I had found I was maintaining or seeing very slight improvement in hair thickness. Ran across the study for "BeauTop" in humans and decided to try it. I must be an outlier because I felt like the improvement was noticeable within 3 weeks. I thought to myself, this really can't be working this well, did some more research, and found this study (abstract I'll post below). In short, this actually seems to lead to noticeable increased thickness for me.Interesting study (in animals):"Minoxidil and finasteride have been approved to treat hair loss by the Food and Drug Administration. However, the further elucidation of treatments for hair loss, including those using Chinese herbal medicine, remains important clinically. BeauTop (BT) is a health food supplement which contains Ginseng radix, Astragali radix, Radix Angelicae sinensis, Ligustri fructus, Rehmannia glutinosa and Eclipta prostrata (Linn). Susbsequent to oral administration of BT at 0.6 g/kg/day to wax/rosin‑induced alopecia in C57BL/6 mice, BT significantly induced hair growth at day 8 compared with control treatment (P<0.05). The expression levels of epidermal growth factor (EGF), and fibroblast growth factor (FGF)‑7 were increased compared with control animals on day 8. In contrast, levels of FGF‑5 of the BT group were reduced compared with the control on day 12. There were no effects on the expression of insulin‑like growth factor 1. The results demonstrated that the mechanism of BT improving alopecia is potentially associated with modulation of EGF and FGF‑7 levels. Taken together, it is suggested that BT may have a potential effect of the promotion of hair growth."(from "Hair growth is promoted by BeauTop via expression of EGF and FGF‑7")edit: my hair situation was already improving but it seems like my hair is now a lot fluffier, a lot less brittle, the hair that is growing gets longer without breaking.I ran into an old acquaintance at a club, 20 years younger, and she was like "YOU HAVE HAIR!"... which kind of freaked me out because I didn't really realize I had an obvious issue when I knew her 5 years before lol
