I do have curly hair, I usually just use regular shampoo, and I don't like the feel that conditioners leave to my hair, but I found, that vinegar is great! So if I feel that my hair need some extra care I rinse them with vinegar after I washed them.
Also rinsing my hair with cold water leaves them more shiny and not as dull.
I try to not put any extra chemicals in or on my body, so that has worked great for me, also camomille or peppermint tea are great to rinse hair with.
Let me know if you have more questions.

Hi there!
I use Aveda's Be Curly shampoo and conditioner. It's great! Most store brands that are laden with parabens and silcone irritate my scalp. I use mostly Eufora products which have defintely thickened my hair but the Be Curly really boosts the curls with little product.
Hope that helps!
