Excellent Product

This by far is the best product I have used to tame frizz. My hair remains frizz free and smooths and softens my hair. The smell is unique. Would prefer fragrance free however, the smell is not unpleasant but a cross between cocoa and coconut scent. Highly recommend this product!
