Julia Youssef, Assistant Vice President, L'Oréal Technical Center answers your frequently asked questions about hair color:
Hair Looks Flat
"I just colored my hair, but the color looks flat. How can I give my hair life?"
Don't pass judgment on your new hair color until you've had it for a week or more. It needs time to settle in and may change in appearance. If after a couple of weeks you're still unhappy with the results, you can break up the solidity of your color by switching to a product or a process that puts more than one shade in your hair. Next time, you may want to try L'Oréal Couleur Experte, an easy-to-use two-step system that includes a coordinated base color and highlighting kit. It comes in 24 shades of red, brown and blonde, so it's a good option for everyone.
Highlights Turn Brassy
"My highlights always turn brassy over time. What can I do to prevent this?"
Always use shampoos, conditioners and treatments specifically intended for color-treated hair. They tend to prevent fading of highlighted hair tones, a problem that often results in bleachy or brassy-looking highlights. Also try to avoid excessive exposure to sunlight and chlorine, which literally bleach color out of the hair.
Color Gone Too Light
"My new color is too light. What do I do?"
Simply wait a couple of weeks and recolor, using a shade one, two or even three shades darker.
Too Dark Color Solution
"My new color is too dark. What do I do?"
Simply wait a couple of weeks and see if (a) the excess color fades, or (b) you get used to the new color. (Sometimes new hair color is so intense and, well, "new" that people perceive it as too dark, when in fact, it's just more saturated.) In either case, you're set. If not, just wait until you're ready for your next touch-up, probably four weeks. Use the same brand, just a shade or two lighter.
Fixing Mousy Brown Color
"I dyed my hair brown but it came out mousy, how do I fix it?"
Wait at least a week before doing anything. Has the color improved? Do you like it more? Great! If not, try recoloring using the same brand and the same level (dark blonde, medium brown, etc.) but with a different tone. Try something with the words "warm," "gold," "copper," "bronze" or "auburn" in its name. The new, warmer color will combine with the old, mousy color and give you a rich brown.
Blonde Gone Brassy
"I dyed my hair blonde but it came out brassy, how do I fix it?"
Wait at least a week before doing anything. Has the color improved? Do you like it more? Great! If not, try recoloring using the same brand and the same level (dark blonde, medium brown, etc.) but with a different tone. Try something with the words "cool," "ash" or "iridescent" in its name. The new, cooler color will combine with the old, brassy color and give you a rich brown.
