This Redken Bonding Concentrate Ph Sealer is formulated to work as the final step in the Redken Acidic Bonding Concentrate regimen. It is designed to quickly seal the hair cuticle, providing instant and lasting surface recovery. Utilizing pH technology, this product helps to rebalance the hair's optimal pH level after chemical services or intense treatments, which can often raise the hair's pH. Consistent use helps to strengthen hair bonds internally for improved resilience against breakage and damage. Ideal for all hair types experiencing dryness, rough texture, or damage from coloring, perming, or heat styling, this sealer supports smoother, more manageable hair with enhanced shine and strength.
