Rated 5 out of 5 by from Great product! This is one of those products that I will continue to repurchase as long as they produce it. The smell alone is the best part, my clients always ask me to use the spray that smells good on their hair. I love that on top of smoothing it doubles as a heat protectant and can be used wet or dry.
