Thanks for your response, in the meantime, is there anything I could do to stop it worsening if it is the case that it is receeding. I've heard of using shampoo containing certain things etc. but I'm not too aware of these sort of things.
It's such a shock for me because I could never imagine being bald at a young age, obviously when your in your 40 / 50s it's a different story but I really wouldn't want it to get any worse than this (I know it's not bad) for another 10 years :/
Cheers for any help.
