Same here, I shit you not, mine started going in the space of two haircuts. Lol
I was always destined to go bald, my old man is, but the style back in the day was the mullet and blonde streaks, I think that killed my hair, made it go like straw. I can remember it now, full head of thick hair before, the next haircut there was a hell of a parting, I was squirming uncomfortably as my scalp was revealed, the hairdresser was taken aback. Lol
