Apologies if this has been asked before.
Quick explanation regarding my awful hair. It is;
Fine
Grey
Fluffy
Moderately wavy
Coloured with various blonde shades
Has lots of little broken strands that stick up and have a life of their own
Shoulder length
It only looks Ok if blow dried and I do straighten it but not too much (just once or twice a week). I'd like to lay off the heat treatments to enable it to repair and become more healthy-looking but I wouldn't like it to be poker straight.
Would a keratin treatment be any good for me or do you have to have it straightened to within an inch...?
