As the air gets cooler and progressively drier, your scalp is going to need some extra care. If dryness is your issue, Living Proof’s latest is coming to the rescue. This scalp treatment promises lasting hydration thanks to the hyaluronic acid in the formula, which forms a microscopic “patch” over your scalp that not only adds moisture instantly, but keeps your hair hydrated throughout the day with time-releasing technology. The treatment officially launches everywhere in February 2019, but the product is so good that Sephora is selling lab samples of the stuff this month.
