L'Oréal Professionnel's Smartbond Step 3 Conditioner is a hair strengthening system that has been specially developed to protect bonds while colouring, highlighting and straightening. Promoting softer, stronger and shinier-looking locks post-processing, the fortifying formula follows the in-salon treatment to maintain strength and condition of hair at home. Helping to protect colour and prevent damage during the colouring process, the bond-strengthening conditioner will leave the hair fibre feeling stronger and healthier. Designed to work in synergy with L'Oréal pre-lighteners and colour products.
