Help on african american hair growth?

I am an afr. amr.teenager too. I take hair skin and nail vitamins thats basically what hairfinity is but it has MSM. I took hairfinity for 2 months and it is very expensive so I decided to make knock off Hairfinity. I take hair skin and nail vitamins and add the MSM to it, same thing lol. Hair skin and nail vitamins have all the essential vitamins for hair. I take 3,000 mg of MSM, Hairfinity has 1500 mg. You cannot overdose on MSM. They recommend you take 1,000 to 8,000 mg. My hair is growing. Do know that MSM changes hair texture. It makes it better. Now my hair is growing. Ive decided to keep the heat out of it. I dont get perms. Nothing. You want to try and keep it up. Try not to comb it alot. No rubber bands only scrunchies. Moisturize daily. I use coconut oil and pure Jamaican black Castor oil. Wash every week and a half. You can buy those vitamins from CVS, Rite Aid, WalMart etc! For breakage and shedding I take odorless garlic. I take one a day. It stops breakage and shedding. Also be gentle with your hair. And get your trims every 2-3 months. You are black do not get your hair trimmed more than your hair grows. They claim out hair grows 1/2 in a month, whatever. Anyways hope I helped :)
