Why Asian Stylists Recommend It
Reaching cool Korean tones on black hair takes several bleach rounds, and coarse Asian hair holds that damage longer than fine hair; a bond shampoo you use daily keeps rebuilding structure between appointments instead of only at the salon.

Best for
Bleached or highlighted Asian hair worn in latte, ash, or blonde tones that needs gentle daily upkeep.
Avoid if
Skip if your hair is virgin and undamaged — you are paying for repair chemistry you do not need yet.
Why we recommend it
No.4 is the everyday shampoo in Olaplex's bond-repair system, built to keep rebuilding broken links inside the strand while it cleans. That matters most for Asian hair lightened to a latte or ash tone — dark hair has to travel through several rounds of bleach to get there, and each round breaks internal bonds that leave thick strands feeling straw-like. It lathers well on dense hair and rinses clean without a stripped, squeaky finish. Treat it as maintenance between salon visits, not a one-wash fix: the repair is cumulative, built over weeks of steady use rather than felt after a single shampoo.
