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.
A surprising number of testers revealed a dirty secret: stripping down when coloring to avoid staining clothes. If that's not your style, wear an old button_front shirt or robe that way, you won't have to lift anything over your head when it's time to rinse. You can also lay down garbage bags instead of covering surfaces with towels or sheets, which can soak through and need washing. Keep your chapstick handy : There's nothing worse than ending up with stripes of color on your forehead. Rather than using a goopy salve to protect skin from dye, glide a clear solid lip balm along your hairline, Hill says: "Its small size makes for concise application."
