Giovanni Root 66 Max Volume Shampoo increases volume in limp, lifeless hair. The natural formulation cleans and adds weightless bounce, strengthens thin, fragile hair and protects fine hair from damage while building body. Root 66 is formulated with soybean protein to strengthen strands, and botanical extracts and oils that hydrate naturally, instead of coating hair and leaving it greasy. Contains Horsetail Extract, a healing herb, rich in nutrients and high in silica to help keep hair strong. Wash in bounce, wash in strength, wash in body! Contains zero sulfates.
