Hyaluronic acid has become an increasingly popular hair care ingredient. HA is a humectant that binds and holds in water, meaning it can help your strands retain moisture within the cuticle. Then to help trap in the water, it also contains a blend of oils, like avocado, argan, and almond oil. Finally, it’s topped with pineapple enzymes to help dissolve buildup.
