Some products are for regular hair and some for wavy hair. I will discuss them in a second.
My first recommendation is to try a chemical-free shampoo and conditioner. It is not necessarily natural. It is very important for you to know if the products you buy have ingredients in them that are natural. There are many products on this page that don't contain any natural ingredients, but don't make your hair look too much better. Another great recommendation is a natural hair conditioner and shampoo. I can't think of any more natural way of keeping your hair clean! Here is a list of my favorites. The most important thing is to find a product that actually works for your hair. I am so confident of this fact that I have found a lot of good brands that don't have ingredients in them. I have even found a few great formulas that don't contain ingredients. Some of them can be found here.
The top natural products for hair include Coconut Oil, Avocado Oil, Aloe Vera, and L-Ascorbic Acid. You may also want to consider Aloe Vera and Almond Oil as natural beauties that will also help keep your hair beautiful.
