You love your freshly colored locks, but after a few days they start to look a hair off: dull, orangey, or not blond enough. Rita Hazan Foaming Color Gloss can fix that. First pick the foam that suits your needs. (The yellow formula boosts gold tones, the clear one enhances shine, and the violet cuts brassiness.) Then apply a pouf’s worth after shampooing in the weeks following a dye job to keep the shade truer longer.
