All of these products are a great combination and they are filled with the best natural ingredients! My favorite out of this combo is the Tea Tree Mint Hair Wash, since I have low porosity hair this shampoo breaks down all of the product that was in my hair without stripping my hair. Another good thing I could tell even after the first use that my hair did not shed as much as it did before. And just like the Hair Serum a little goes a long way!!!
