Shampoo and conditioner recomendations?

I have naturally wavy hair that I can blow dry straight or use a difuser and have curls. It can also get frizzy and oily at the same time. So, I was wondering if any one had any suggestions for a shampoo/conditioner that can combat both of these issues. The more suggestions the better. Thanks.Shampoo and conditioner recomendations?
I use Nioxin, Paul Mitchell and Sleek look - they are all good for naturally curly hair. There is also Kenra, made for curly hair.Shampoo and conditioner recomendations?
My girlfriend uses Herbal Esscensas
Aussie shampoos and conditioners are nice, they seem to be more natural and are low cost
