This is a Beyond Beauty product which means it has been sourced, tried and tested and finally declared one of the most new and innovative heroes out there. The No. 3 Hair Perfector from OLAPLEX is a weekly at-home treatment, not a conditioner, that reduces breakage and visibly strengthens hair, improving its look and feel. This global bestselling formula repairs damaged and compromised hair, strengthening and protecting its structure. It works to restore a healthy appearance and texture to the hair. Apply a generous amount from roots to ends on damp, towel dried hair. Comb through once and leave on for a minimum of 10 minutes or more. Rinse from hair, shampoo, and condition. Use once a week or two to three times a week for damaged hair.
