One of our best sellers! No.3 is an at-home treatment, not a conditioner, that reduces breakage and visibly strengthens hair, improving its look and feel. It will restore your hair’s healthy appearance and texture by repairing damage and protecting hair structure. OLAPLEX restores damaged and compromised hair by repairing from the inside out with their patented single ingredient, bis-amino diglycol dimaleate. How To Use: 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. (The longer the better!) Rinse from hair, shampoo, and condition. Use once a week or two – three times a week for damaged hair. Available in 100ml or limited edition bonus size of 2250ml.
