About This Product

The Keranique Follicle Boosting Hair Serum is a 2 fl. oz. scalp-nourishing, fiber-fortifying, ultra-lightweight daily treatment serum developed to support scalp health. Its standout technology centers on Keranique's proprietary Keratin Amino Complex, which selectively bonds to natural keratin protein found in your own hair fibers, strengthening each strand from shaft to tip while helping condition the outer cuticle layer and reduce the look of split ends. The formula is further powered by Acetyl Tetrapeptide-3 paired with Trifolium Pratense (Red Clover) Flower Extract — a duo known as Capixyl — which works to nourish the scalp and support the feel of a calm, comfortable scalp over time. Botanical actives including Panax Ginseng Root Extract, Laminaria Digitata (seaweed) Extract, Malus Domestica Fruit Cell Culture (apple stem cell) Extract, and Arctium Majus Root Extract nourish the scalp environment, while Panthenol and Niacinamide condition and strengthen each hair fiber. The formula is alcohol-free, sulfate-free, dye-free, paraben-free, gluten-free, and phthalate-free, and is cruelty-free and safe for color-treated hair. With daily use, hair looks visibly fuller, thicker, and shinier, with a sheer, weightless, fast-absorbing finish that never feels heavy or greasy — ideal for anyone who wants a scalp-targeted, leave-in treatment they can build into their routine. How to Use Apply to dry or towel-dry hair by spraying the serum directly onto the scalp. Massage gently with fingertips to encourage absorption. Do not rinse — leave in as a daily treatment. For amplified volume and thickness, follow with Keranique Lift and Repair Treatment Spray during styling.
