Similar to the Touch of Keratin, this Magic Potion by Simply Smooth goes above and beyond to protect, repair, and encourage healthy hair. My baby fine hair does not like heavy product and this one doesn't disappoint! I can use enough to cover my hair, root to tip, and it doesn't weigh it down. My hair is silkier and softer with continued use. The difference in how well my hair straightens is truly amazing! I can't thank my stylist enough for introducing me to this product. I have hair that is just past my shoulders and I can use 4-5 squirts without turning my hair into a gunky mess. My full size bottle has also lasted me more than a year at this point.
