This is the first product I've ever used that gave me noticeable results after just one use. It has been a game changer for my hair. I have fine, wavy hair that gets oily within a day or two of washing, so I wash it pretty often. After using this product a few times, my hair feels softer, silkier, bouncier, and more hydrated without feeling too oily or too stripped. My scalp also feels much cleaner overall, and I've had no irritation. I noticed these results after my very first use and every time I've used it since, I've gotten the same results. I'm obsessed, my favorite product from Skalli.
