I have noticed since the begining of Feb., that my hair loss has decreased quite a lot. I cant really see much new growth yet but at least Im not losing any more. My hair loss lasted about 6 months and started about 3-4 months after I started low-carbing. I cant really think of anything different I had done the month previous to the loss slowing down...I had been taking biotin, and lethicin for a long time. The only thing different I did was add extra magnesium supplements, which I didnt think aided in preventing hair loss but maybe it did.
