Effective oil removal from hair is very important. For heavy oiling,consider shampooing twice .Vilvah’s shampoo is made of natural cleansing and foaming agents, that produce ample foam when water is added. To maximize lather, apply an ideal amount to wet hair and increase water use rather than product quantity. Repeat during the second shampoo round for thorough oil removal. We suggest you to always use a conditioner after shampooing. If you are having dry hair we suggest you to start using Vilvah Cream Conditioner.
