Kerave Hair We will begin with essentials - moisturizing shampoo and conditioner. Shampoo should contain silicones, fatty alcohols, wheat proteins, and/or cationic polymers. These ingredients will help strengthen and protect your hair from environmental damage. Use a heat activated version if you regularly make use of a flat iron, hair dryer, or curling iron. It is best to use a conditioner after washing to replenish the moisture which stripped through the harsh hot water. If you have oily hair, use a volumizing or fine hair conditioner during the ends of hair only, carefully avoiding the hair follicles.
