Betraying its chic, minimalist appearance, this brilliant bottle holds miracles. So much more than a hair treatment, OLAPLEXs four-step ritual is a system that permanently rebuilds the damaged disulphide bonds in your hair which are compromised as a result of colouring, heat styling and everyday wear and tear. This concentrated leave-in treatment is an excellent addition to any hair care routine as well as being a must-try for those with bleached, coloured or chemically-treated hair. As much a hair styling product as it is a intensive hair treatment, this also promises to strengthen and moisturise, speed up blow-drying time and control flyaways for up to 72 hours as well! Add this to your Olaplex routine by applying after your No 4 Shampoo and No 5 Conditioner to improve the finish of your styling and make sure youre using No3 once a week to vastly improve the health of your locks!
