I've had a lot of success with oiling. I was a vegetarian for 2 years and then became vegan. My hair started falling out in clumps. I bought some oils online for a company and it's really been working great for me. I have my before and after pics in my profile you can see the difference, or I can pm them to you if you'd like.
I've had seborrheic dermatitis since puberty and at one point I listened to the dumbass Ayurvedic and naturopathic people and used various oils on my scalp thinking I would help my hair. Instead of helping I'm pretty sure it aggravated my dermatitis even further and made more hair fall out thru inflammation. If the product does not help reduce androgens in your hair follicles it's gonna be useless long term imo.
Yes, castor oil seems to be working for me. But it's too early to tell. I definitely have some regrowth in previously bald areas and crippled hair is getting stronger.
I use it daily orally and topically with DMSO. Also Stemox daily.
Dermarolling with Lithium Succinate once per week. Been on finasteride for years without any change.
