I have has this problem and I bought Oil of Olay vitamins at the drug store. It grew my hair and my nails. Also, when you wash your hair, treat it gently and squish it like a sponge. It makes it thicker if you squish the shampoo, conditioner in it as if it were a sponge. Comb carefully without pulling and snagging.I put 2 types of detangler on my hair before I comb it at all when it's wet. Hope this helps. Not an overnight cure, but it does work.
