curly haired girl needs your help!

Dear readers, I need help for my 12 yr old cousin who has very dry,curly hair. I am no hair expert and have straight hair. She tells me her hair was damaged when she brushed her hair,not combed, when wet and i can see the damage which is a thin top layer that is very near to straight but not in a good way. She has the new Pantene Dry to Moisturize products but only the Shampoo, Conditioner and a square bottle that just says 'Treament' she thinks she needs all of them but does she? She owns the Ouidad 13-peice package but is not sure which to use in order....more
