Betraying its chic, minimalist appearance, this brilliant bottle holds miracles. So much more than a hair treatment, OLAPLEX’s three-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. A once-a-week at home treatment, this silky fluid reforms shattered hair bonds in between your salon or styling sessions, so you can carry on maintaining your favourite hair colour and style without the worry of damaging your locks beyond repair. The star ingredient is bis-aminopropyl diglycol dimaleate – sounds science-y but it will strengthen and repair damage post-colouring, bleaching or heat styling (or even if you’ve never tainted your locks with colour or tongs!) Use as a leave-in, overnight treatment or as a luxe 10-minute pre-wash treatment and see the incredible results for yourself.
