Smart Bond

Smartbond is a new colouring technology that strengthens your hair during and after a colour service. It contains an additive that is added during your in-salon colour treatment to help prevent further damage.

Your hair fibre is made up of Keratin chains that are linked by bonds. Smartbond targets weaker parts of the bonds and helps to reform them and improve the overall look and finish. Smartbond is highly recommended for clients that lighten their hair with bleach, or frequently colour their hair, to help maintain the strength of the hair.
