The Kérastase Nutritive Lait Vital 200ml Duo is designed to treat normal to slightly dry hair in a handy duo pack to ensure you don\'t run out. This conditioner is fortified with glucose, proteins and lipids. These help to feed any nutritional deficiencies within the strands and shield the surface during the drying process. Such deep conditioning can weigh down hair but not so with Kérastase Nutritive Lait Vital. Even with daily use, this nutritive conditioner leaves your strands light, healthy, soft and supple. The treatment conditions strands from the root to tip. This aids in detangling and adds to an enhanced shine. If your hair is prone to slight dryness then this product is ideal. Targeting vulnerable areas of each strand, it protects against premature drying and leaves hair looking well-nourished and healthy. Product is to be applied to hair that has been washed but not yet dried. Massage in well and leave for 2-3 minutes to allow the active products to penetrate and nourish each strand. Emulsify then rinse thoroughly.
