Re: pimples on scalp/hair loss
If it is hairloss due to stress it could be alopecia areata for which your friend will have to see a dermatologist and get cortizone injections to the scalp. The sooner the friends does this the better. !!!!
If she doesnt do this it will get to a point where reversal would be very difficult if not impossible. Since you firend is a girl...its more important that she take care of this asap.
Guys can be bald and be okay with it eventually. Girls cant!
