Alopecia was stopped on my head with the use of Amla Juice and Ashwagandha. Amla juice is sold at some India stores but the Amla or Amla C and Ashwagandha can be bought at Sprouts, www.himalayausa.com and some online stores.
I was told by my doctor I had ZERO Vitamin D in my body and no protein uptake either as per my blood results. She even asked if I was vegeterian which I am not as my body was not uptaking protein which is what hair is made of and therefore I had Alopecia.
Googled what caused Vitamin D and protein to be blocked and found the sugar Splenda (yellow package of no calorie sugar) of which I consumed daily. People also wrote in that they had alot of itching on their head when they consumed Splenda. I stopped using Splenda.
I also used Hair, Skin & Nail Vitamins which can be bought at drug stores and vitamin stores. That helped my hair grow back in after about 6 months BUT it would NOT stay in as my hair fell out all over my head and my scalp was quite visible.
Then found AMLA and Ashwagandha and after 6 weeks of use it totally stopped my hair fallout.
Just google Amla or Amla C (it same product) and Ashwagandha and you will find lots of information on it. I also use NEEM which can be bought at same stores.
My hair has all grown back in and I continue to use Amla shampoo and hair products. You can also buy Amla Oil ( which has a very strong smell) and Amla powder. Just mix the powder with water and apply to hair/head. It will tighten the hair follicles. The Amla tablets and juice I consumed.
Hope this helps others.
