community A new study by Deng and colleagues set out to explore differences between balding and non balding scalps...

39 upvotes 4 years ago

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

community I have been using castor oil for my brows for 2 weeks , and i already see visible difference. Could i also apply it to my scalp?

12 upvotes 5 years ago
