Wave Builder Wash in Waves 6.9 fl. oz.Smart wavers never use any old shampoo or whatever they find in the shower! The wrong shampoo can reverse days of wave work, make waving harder, and make your waves look dull and dry. Many shampoos strip hair of essential moisture and oils with harsh surfactants. Wave builder Wash in Waves Wave Saving Shampoo is WAVE SAFE (TM), hair healthy and never strips – but it still cleans hair and scalp fully and leaves hair soft and refreshed. Enriched with keratin and collagen amino acids.
