Yes it's candida messing with your body and depeleting all the vitamins and minerals you need for healthy hair and nials. I use 5000mg of biotin twice a day, my hair was falling out like crazy, handsful at a time, I was afaid to wash it cause soo much would fall out. I started using the biotin and within a one months time it stopped falling out and started growing back. I was so tickled to have all those little baby hairs pop out. Make sure you get 5000mg not 5000mcg, mcg or micrograms are not a large enough dose.
