I'm an 18 year old female, I've had long thick hair all my life but the last few months I've experienced so much lair loss, I can just touch my head or bush it once and so much will come out. It's not in patches, just seems all over. I haven't changed shampoos etc. or changed anything about my hair care, exercise, diet etc. Only started since I went to university, however I am not stressed so don't think it's stress related, pleas help! Thanks :)
