I use a natural tea-tree oil shampoo and conditioner. It's similar to what they sell at Trader Joes. I've heard great things about washing your hair with water + baking soda, then rinsing with water + vinegar, but have not tried it yet. I find diet plays a huge role in the healthiness of my hair -- and I don’t eat added fats, so any article claiming you need nuts and avo for good hair is wrong.
