I'm in my 20's, and I began to notice a single white hair growing from my head. At first I thought it was gray hair, but someone told me white hair can be commonly found if I have a small birthmark on my scalp. Well, I have had my head shaved pretty short, and haven't seen any sign of a birthmark.
Now I'm getting even more white hairs. They come out easily, but aren't brittle. The strange thing is, they are stronger than my normal strands of hair, and grow more rapidly. At first, I thought it was an illusion, but it's true that every white hair on my head, is considerably longer than my darker hairs.
Is this gray hair, or a common condition? Could this be some strange, and rare hair disorder? I've never heard of gray hair being stronger and longer than normal hair.
