Kiehl’s offers a wide selection of fortifying hair care formulations to rejuvenate hair no matter your concern. To help lock in moisture and shine, look for nourishing formulas with ingredients like Olive Fruit Oil, Avocado Oil, and Lemon Extract. If you’re looking for a mild shampoo to help revive thin, lifeless hair, reach for a formula infused with Rice and Wheat Proteins. To help smooth, hydrate, and replenish, try a leave-in hair treatment infused with Hyaluronic Acid.
