finally coming to admit it

[hippiehippiehoorah]

I'm an 20 year old male from the UK, i've been trying not to believe it for a while but am finally admitting to myself that im starting to go bald, on the crown and temples.
It kind of upsets me because i still think im too young to be having to worry about this. But i'm going to try what i can to prevent it or just try and slow it down.
I was wondering if anyone would be able to point me in the best direction in respect to medication, treatments or diet, and also i hear people talking about going to a dermatologist but i'm not really sure how to do that in the uk.
Oh yeah and i'm on 10mg a day for anxiety attacks would this affect any potential medication that i might take.

Thanks very much in advance to anyone that replies.
