Revive and enhance your hair with Goldwell Dualsenses Color Extra Rich 6 Effects Serum, a leave-in formula that delivers a host of renewing benefits on both colour-treated and non-coloured hair. Providing nourishment, colour protection and mirror-like shine, the serum has been developed with a FadeStopFormula to minimise colour fading, and utilises Luminescine Technology; an innovative system that transforms non-visible UV light into visible light for amplified vibrancy and colour brilliance. Ideal for thick to coarse hair, its multi-tasking properties help to improve hair elasticity, nourish lengths and ends, and inspire salon-fresh colour. The extra rich formula will leave tresses looking healthy, sleek and radiant.
