shampoo and conditioner. help?

Kay

Alright ladies, I need some help with my shampoo and conditioner!! Over the last couple years my hair has been breaking off, falling out, and thinning. I don't have oily hair, but it is dry and frizzy. It's naturally wavy, and I straighten about 2 times a week. Someone told me I needed to change soap. I have tried a variety of brands. I have used sulfate free and that makes my hair dry. I just need a good shampoo and conditioner that will bring my hair back to life!!
