My mum and my elder sisters all have quite thin hair - one of my sisters has especially thin hair, like, you can see quite alot of her scalp - she has to dye her hair blondish to not make it so prominent. I've deliberately not bleached/done anything drastic to my hair (both my sisters have) so i dont harm it. However since about a year ago (I'm 18) I noticed that when I tied my hair back, with a parting still there, you can see my scalp, and theres definitely more scalp than there was before (I have brown hair so you can see the scalp more clearly). Also i went to the hairdresser the otherday and she commented on how thin my hair was.
My hair is no way near as bad as my sister's, but I really dont want my hair to thin any more - although it seems to run in all the women in my family. Would it be silly to go to the doctor now, when its not really THAT much of a problem, or wait til its really bad? Meanwhile, can anyone recommend any over-the-counter stuff that will help?
