Refreshes faded brunette tones between salon visits
Adds depth and shine without heavy residue
Description
Jerome Russell Color Bomb Cool Brown 300ml is a temporary colour mousse that refreshes dull brunette hair. It adds cool brown tone while helping to disguise faded colour and unwanted warmth.
This tinted foam is ideal between salon visits or for a quick shade update. The lightweight formula adds visible depth and shine without making hair stiff or sticky. It gradually washes out in a few shampoos, so there is no long-term commitment. Suitable for most natural or coloured brown hair, it works best on light to medium bases. Use to revive colour, blend root regrowth or deepen your existing brown shade for a richer, cooler finish.
