Help for tangled frizzy hair?

I have to exact same hair as you. For shampoo and conditioner get Matrix sleek looks. It's perfect for my hair and probably will be for yours to. Then if you do flat iron your hair I would use Paul Mitchell super skinny serum which i use everyday. If you want to make it look good straight I finally found the perfect mousse try Paul Mitchell Extra body styling foam. I just got it and for the first time I can wear my hair naturally and it looks so good. Hope this helps :)
