This study found that procyanidin oligomers from apples and barley may stimulate hair growth by promoting hair epithelial cell proliferation and protecting them from apoptosis via MEK activation in a murine model.
Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved haircounts over 24 weeks.
A user is considering using Bare Anatomy's Advanced Hair Growth Serum, which contains Redensyl, Anagin, Baicapil, Rosemary, and Biotin, for thinning hair. Reviews are mixed, with some users skeptical about its effectiveness compared to minoxidil.
Teak leaf extract shows potential as a mild hair growth promoter for androgenic alopecia, with similar positive trends to minoxidil but without significant side effects. It can be made at home using dried teak leaves and ethanol, though its effectiveness compared to other treatments like finasteride is debated.
The conversation discusses using a custom topical from Skin Medicinals containing latanoprost for hair loss, which helps move hairs into the anagen phase. The user is curious about the cost and effectiveness of this treatment.
The conversation is about sourcing raw ingredients like finasteride, dutasteride, minoxidil, and tretinoin for making hair loss topicals. A suggestion is made to check Anagen Inc. for these ingredients or contact local suppliers for bulk purchases.
Does caffeine stimulate hair growth or only slow hair loss?Caffeine stimulates hair follicles in laboratory cultures, and one open-label trial in 210 men found a 0.2% caffeine topical non-inferior to minoxidil 5% on an anagen-ratio endpoint; there is no placebo-controlled evidence that it regrows hair, and none at all in alopecia areata or telogen effluvium.
How does latanoprost work to make eyelashes and possibly scalp hair grow?Studies report that latanoprost, a prostaglandin analog, lengthens the anagen (growth) phase of hair follicles, which is the mechanism given for the eyelash thickening seen in glaucoma patients; on the scalp the evidence is one 16-man pilot study and animal work, so the effect there is unproven.
