Why Asian Stylists Recommend It

Why we recommend it
The Acidic Bonding Concentrate shampoo is the cleansing step of Redken's bond line — a low-pH wash for bleached, color-treated, and over-processed hair. Getting Asian hair to ash takes heavy lifting that leaves the strand porous and the cuticle raised; washing at an acidic pH cleans without swelling it further, so hair finishes smoother and holds its tone instead of rinsing color away week after week. It suits chemically treated hair that a general shampoo leaves rough and fading. Massage it into the scalp and rinse through the lengths, then follow with the matching conditioner. It strengthens and protects color rather than clarifying, so hard-water buildup still wants an occasional chelating wash.
