Kérastase Specifique Dermo-Calm Bain Vital Shampoo Duo is an innovative formula which soothes sensitive scalps. The botanical extracts gently cleanse while moisturising the scalp and calming irritation. Kérastase\'s formula is hypoallergenic and free from silicone, making it ideal for dry, sensitised hair and scalps. Infused with comforting Calophyllum oil and glycerin, the shampoo repairs and protects from the cuticle to the tip. Alongside a refreshing menthol extract, the formula removes impurities leaving hair light and shiny, while reducing itchiness to create a more comfortable-feeling scalp. Plus, Kérastase\'s specially-formulated shampoo also contains piroctone olamine, which has anti-bacterial and anti-fungal properties which help to control the root cause of dandruff. For best results, use as part of your usual hair-care routine. Apply to wet hair and massage through the scalp in circular movements to activate microcirculation. Emulsify and rinse thoroughly. If desired, repeat and leave the product in for a few minutes. This second wash will encourage the active ingredients to penetrate deeper into the hair fibres, nourishing the lengths and scalp. Rinse thoroughly and style as normal.
