The best shampoos for damaged hair, according to experts
Although this is technically not a shampoo, Jordan recommends this pre-wash, which she says helps relink the bonds that make up the molecular core of your hair. Not only does it build up those bonds, but it also helps reduce breakage, split ends, dryness and frizz, according to the brand. To use a pre-wash, dampen your hair and apply it from root to end and leave it on for three to ten minutes before rinsing; you’ll then follow it up with the bond repair shampoo, according to Olaplex.
