My daughter has my hair, which is both lucky and unlucky for her.
Unlucky because it's so fine that she will probably never have a long, thick, swishy ponytail but also, totally lucky because I know how to deal with it.
My mum has really different hair to me so dealing with mine was a lot of trial and error. She always thought it needed to be trimmed but no amount of taking off the ends was going to make it less scraggly. It's just is how it is. Or how it WAS pre-GHD.
