Catalase is an enzyme that like many things apparently depletes as we age. Whether this enzyme can be replenished topically through the hair and skin is something I do not know but the shampoo did a good job hydrating my hair leaving it soft and manageable. The product is a clear light low suds gel and has a distinctive minty fragrance. I am most impressed with how my scalp felt like it was somewhat exfoliated and had less skin cell build-up. The mild non-drying cleanser and foaming agent used is derived from coconut oil so it is less harsh than some other commonly used ingredients. This is a small 8 ounce bottle and my long hair required a significant amount so I don’t expect the bottle to last for more than a couple of weeks. So far I like the product and have had no negative skin or hair reactions, but if sensitivities exist it may be wise to check the ingredient listing. Read more
