If only forty actually was the new thirty. As temperatures rose this past weekend in the GCC and across Europe and North America, anyone daring to step outside was sure to apply sunblock. But what about protecting our hair and scalp? Paris-based hair brand, Kérastase Bain Vital, introduces its first hyperallogenic shampoo formulated with anti-inflammatory peppermint, a soothing ingredient from willow extract and non-greasy glycerin to hydrate and protect the scalp from redness and irritation. Use as a post-swim tonic to remove drying chlorine or dulling saltwater residue, or even to treat scalp psoriasis; but, the effects are not lasting, so do expect to wash and repeat.
