How do I keep my curly hair from frizzing?

Shampoo and conditioner often don't really make a difference. Try switching out your shampoo every two or three days, it works for me. And also, get Paul Mitchell Super Skinny Serum. It's a little bit expensive, but it realllllyyyy works! You can get it at just about any hair salon for around $15. I promise it'll be worth it haha(:
