I tend to buy DD kid's shampoo adn conditioner 2 in 1 I find her hair really does need the conditioner bit, and I also do it with seperate conditioner as well every so often. Her hair is really fine and fly away.
I use a detangler sometimes before brushing as it can get quite knotted when longer.
However DD has just had her hair all cut into a short choppy bob, so many of our hair problems are on hold for a while.
