Kérastase Nutritive Hydrating Shampoo for Fine to Medium Dry Hair is a hydrating shampoo that gently cleanses, replenishes moisture, and adds deep nutrition to normal to dry hair. Suitable for straight, wavy, curly, and coily hair textures, and fine to medium hair types. It addresses hair concerns like dryness, shine, damage, split ends, and breakage. The shampoo gently removes product buildup, smooths, softens, and detangles hair while deeply hydrating and nourishing it. Key ingredients include plant-based proteins that nourish hair and help retain moisture, and niacinamide, which locks in hydration for long-lasting hair strength. The lightweight hydrating formula conditions and detangles hair while boosting shine. It has a fresh and floral fragrance with top notes of green, middle notes of fresh flower, and bottom notes of powdery and musk. Clinical results showed hair was conditioned, detangled easily, and 90% shinier versus unwashed hair. Suggested usage includes applying to wet hair, massaging to lather, rinsing thoroughly, and following with a conditioner or hair mask. Pro tips recommend applying to scalp first, emulsifying with water, and combing through mid-lengths and ends before conditioning. For maximum hydration benefits, it can be paired with Nutritive Heat-Protecting Styling Cream and Nutritive 8H Magic Night Serum (sold separately).
