Back when I was doing Atkins and on a low-carb diet board there was lots of talk about this happening. They recommended taking Biotin. I was impressed with the women reporting great results with their hair and nails.
I've been taking one 1000 mcg tablet of Biotin a day. It's cheap and can be bought at Wal-Mart. I wear acrylics so my fingers nails are already damaged but I hope that the Biotin keeps them from becoming more so. My toe nails are very strong and grow like crazy. My hairstylist thought my hair was breaking until she realized that I had a ton of new growth all over my head. My hair has never been this great.
So, I don't know if it is the Biotin, all the other vitamins I pop, the healthy diet, the tons of water, or what. All I know that I'm not stopping to find out.
