After taking Nutrire’s scalp quiz, S. 2 Renew was recommended for my normal scalp, and it ended up being exactly the right fit. The personalized quiz made choosing a shampoo simple. The formula is GOOD. Ingredients like glycolipids, panthenol, hyaluronic acid, aloe vera, caffeine, hydrolyzed wheat protein, pumpkin seed extract, and nettle help support scalp health while keeping hair soft, hydrated, and manageable. My hair is down to waist and pretty thin overall. Most shampoos leave my hair feeling stripped, but I noticed after shampooing with S. 2 Renew it feels truly clean, moisturized, and balanced. The shampoo texture is smooth and luxurious, rich lathering, a little goes a long way, and the suds spread easily through the hair. My hair feels clean, lightweight, and wayyy noticeably softer after each wash. I'm very scent sensitive, like will not buy something if the scent is too strong, but the S. 2 Renew scent is mild, fresh, clean, and sophisticated. Not overpowering, and enough to last throughout the day into the next even after sweating or sleeping. The packaging is also so good. Minimalist bottle looks spa-worthy, and elevated on my shower shelves. If you’re looking for a premium shampoo with a focus on hair health, hydration, scalp nourishment, and stronger hair, Nutrire S. 2 Renew is well worth it. The combination of ingredients, personalized product matching, beautiful packaging, and excellent results makes it one of the best scalp-focused hair products I’ve used recently.
