Our Level 3 is for curly hair. It is a 2-in-1 shampoo/conditioner all in one. Curly hair is defined by ringlets (aka coil or spring-shaped texture). This hair type frizzes up very easily in poor weather and is very easily damaged. This is why it is especially important to keep your hair healthy and happy with our Revitalizer product. Our 2.7 oz is perfect for the person on the go and travel carry on.
