"There is definitely a movement happening where women are choosing more ingredient_conscious beauty products," says Chelsea Smith, master colorist for Madison Reed, which makes at_home hair color that's touted as the first "six_free" formula. This means it doesn't include what they consider to be six questionable ingredients commonly found in hair_color formulas: ammonia, resorcinol, parabens, phthalates, PPD and gluten.
Skip the suds: It makes sense. Washing hair washes out color too. One way the Beauty Lab tests color fading is by repeating washing cycles, because just plain water (not to mention shampoo's surfactants) can leach dye molecules from strands, the Lab explains. "Wash colored hair every other day at most," Hill says. Switch products regularly : The Beauty Lab has found that using a color_depositing shampoo, conditioner or hair_gloss treatment once a week between dye jobs can revitalize hair color. Try Seal holders Pantene Pro_V Brunette and Highlighting Expressions Shampoo and Conditioners. Gloss it up: Like lip glosses for strands, hair glosses leave a hue_boosting hint of color and shine.
