Are you massaging it in circles or are you doing a rubbing motion?
My hair doesn't break when I massage my scalp but....
I was reading up about hair on this UK trichologists' (sp?- hair specialist people) website and under Afro hair it said that one should never massage the scalp with this type of hair because it will break off. When I read that all I could think was "oooooo...I wonder what the ladies at LHCF would have to say about this?"
Rubbing.
