Olaplex has done it again! Everyone has been asking for a purple shampoo for dry, damaged hair. Purple shampoos are notorious for drying out your hair. Olaplex has combined its famous hydration with an intense purple pigment. You will not sacrifice a deep purple tone while repairing and nourishing your locks. This will be your new game-changing product if you have dry or damaged hair and want to remove any yellow or brassy tones. I like to use the purple shampoo once a month, but if your hair tends to go brassy, use it once you see an unwanted tone appear.
