Betraying its chic, minimalist appearance, this brilliant bottle holds miracles. So much more than a hair treatment, OLAPLEX’s 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 an 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 you’re using No3 once a week to vastly improve the health of your locks How to use:Apply a very small amount to damp or dry hair, concentrating the product on your mid-length to ends. Comb through and style as desired.
