Hair Type Wavy Hair
[I received this product in exchange for my honest review] Love an easy spray leave-in! This one bottle will last me a long time, and makes my hair super easy to comb through after washing. My hair is pretty curly naturally, and prone to frizz, plus I live in the desert and it gets super dry especially in the winter. Glad to have found this!

Hair Type Very Curly Hair
[I received this product in exchange for my honest review] This dried out my hair. I have medium, curly hair, and using this I might as well have just used water. On its own my hair usually isn't super dry, but I do prefer hair masks over everyday conditioners so I don't have to use extra products for reference. Using this with the rest of the line, and my normal shampoo/conditioner made my hair feel dry and frizzy.
