No scientific studies. But it's use has been documented and you can check it for yourself. Search for "castor oil" and "hair" on your search engine and make it filter so you get results for 1999 and 2000, just as an example. Interestingly, among the first hits, a patent for hair regrowth is...
Yes, the androgen sensitivty is the evidence. But it's just that, an observation. So like I said, at one point you can have massive tolerance while pumping in steroids. A short time afterwards you can halt your intake and go bald regardless. The sensitivity being there just means androgens...
Another factor or factors are the root cause. There's plenty of evidence for this by looking at, for example, bodybuilders on steroids. Some of them bald, but some don't even when they're on colossal doses. Yet, when they age, they end up balding regardless. Some of the all-time top names in...
Collecting and maintaining a routine for everything was a major problem. While the regrowth on his temples was really good, he was far from regrowing them fully. That's the take from looking at the pictures uploaded on his discontinued blog post.
I have to agree. His results are more impressive. Although there's some difference to when Chen and Narwhal introduced their drugs (Minoxidil and Finasteride).
Narwhal's regimen states 5% Minoxidil 2ml 2 times a day, Finasteride 1mg and Nizoral shampoo 3 times a week. And I suppose this was...
Yes, and by that I meant that there have been no studies with castor oil being used topically on humans. However, there's evidence for the PGD2 and PGE2 claims. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3982925/)
The guy on here with the most impressive hair regrowth from dermarolling, Chen, used 1,0mm needles twice a day for 5 minutes each. He reported going medium strength without any bleeding. He was also, just like you, using Minoxidil and Finasteride. He would apply Minoxidil after his dermarolling...
I know about PGD2 and PGE2. There's been a craze about that. It just never turned out to be what some expected. And castor oil for topical use has been around for far longer than when that submerged.
You're basically just confirming everything I just said. Castor oil doesn't work, atleast not...
I would suggest starting with dermarolling. A dermaroller is a cheap investment and there's ton of anecdotal evidence from just the past year alone. Also it seems to be working best with Minoxidil, which I see you're already using. To see some success by other members on here, check out this...
Like I said. You can't overconsume beta-carotene to cause hypervitaminosis A. Evidence for this is lacking.
"Toxicity studies in animals have shown that beta-carotene is not carcinogenic, mutagenic, embryotoxic, or teratogenic and does not cause hypervitaminosis A."...
There's ton of stuff that is good for hair such as vitamins, minerals, collagen, probiotics, etc. It doesn't mean you'll regrow any hair which was lost through male pattern baldness. It's quite safe to assume at this point that castor oil applied topically on its own won't regrow much hair, if...
So, no scientific studies or even anecdotal evidence to support your bold claim. Castor oil has been mentioned for treatment of hairloss on these forums alone for more than 15 years.
