Full Olaplex system! No 3 is a pre shampoo treatment that is meant to repair and build bonds from the inside out! I leave on for 15 minutes before shampooing! No 4 is their shampoo! A little goes a long way and leaves your scalp feeling clean while using the same bond building technology as no 3! Helps with dull dry hair and friziness too! No 5 is their conditioner! Repairs damage, split ends and leaves hair shiny! I leave on for a few minutes after shampooing! Again uses their bond building technology! No 8 is their newest product!! This is an intense moisture mask, a little goes a long way! Provides just what it says, moisture, shine, and smoothness! (And once again uses the bond building technology!) http://liketk.it/3f6kX #liketkit @liketoknow.it
