Well it's great to have thick hair and it looks more fuller so I will stick to the thick hair. But there is this Pantene shampoo that helps make hair straight.
3 minute miracle works really well with my thick hair!
I like redken.


Don't use pantene, it leaves a waxy residue in your hair that only a stylist can strip out.
