Thanks so much guys for the replies, really appreciate it!! Rootz, thanks and yes, I`ve noticed the sides going back. That`s the problem, I`m 21 and already noticing it, my hair just feels so weak and thin now. What do you mean "unexpected"?. I shall try to get a photo of years ago, I think I may have always had a v shaped hairline but not this far back. Greatjob, are those treatments expensive?? And are the regrowth treatments expensive? Jotronic, just how does the mature/adult hairline develop, do the sides recede during the transition? As I said, My scalp is visible though the front and there is a general lifelessness to the hair. Thanks guys
