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.
