I'm posting this as I'm somewhat confused and a little worried. Every time I get a shower in the morning I rip up from the drain a handful of hair. I am only 28 years old, and I'm shedding like a Shetland Sheepdog. I'm afraid to go out and get a haircut, as I figure it's like rolling the dice, I don't know if it'll grow back. I have a strict reducing hairline, not unlike Drew Carey. It can't be genetics as my father and his father have full heads of hair. I was thinking it might have something to do with my thyroid, but I'm unsure.
