Love this product

I really love this product. If you’re a salon owner add this to your back bar it’s definitely worth it. The only thing I can complain about is how heavy it can be. It tends to make the hair oily if applied to heavy handed. I’ve found that taking 2 inch sections with one/two sprays, then combing through works best. Avoid roots.
