QUESTION: "I use a color-safe shampoo on my dyed hair, but how important is color-safe conditioner?"
ANSWER: Using a regular conditioner certainly won't harm your dye job, but they can extend the life of your hue and protect it from fading.

"They're an important shield from environmental factors," explained Jessica Simpson's colorist Rita Hazan. A leave-in conditioner like Garnier's Color Shield ($6; NEW) is another great option, says cosmetic chemist Ni'Kita Wilson. "It allows more of these protectants to remain on the hair since they're not washed away in the shower."Read MoreLess
