- A low pH shampoo specially formulated for curls, to help preserve curls' delicate moisture balance. When the hair cuticle does not lay flat, critical moisture escapes. To preserve moisture and keep nourishment within hair, curls need a gentle, low pH formula. High pH will raise the cuticle, causing tangles, dullness, frizz and damage. Clear & Gentle is a low pH shampoo formulated to preserve curls' natural balance by helping the cuticle stay flat and closed. Wheat Proteins and Jojoba Oils nourish hair, restoring internal weight and encouraging natural curl formation. Once nutrients, natural oils and moisture are sealed within, curls are stronger, healthier-looking and frizz-free. Begin with a nickel-size amount of shampoo. Gently massage through wet hair and scalp with fingertips and distribute through hair with outstretched fingers. Be careful to never bunch or scrub hair together while shampooing as this roughens the cuticle and causes weakened, frizzy hair. Rinse with warm water and follow with Ouidad VitalCurl Balancing Rinse Conditioner. NOTE: Shampooing every day is not necessary. Shampooing less often allows your natural oils to lubricate and protect your hair.
