" 1. Shampooing the day after you dye your hair It&amp;#039;s one of the most common mistakes, but also one of the most costly. &amp;quot;After having your hair colored, wait a full 72 hours before shampooing,&amp;quot; says Eva Scrivo, a hairstylist in New York City. &amp;quot;It takes up to three days for the cuticle layer to fully close, which traps the color molecule, allowing for longer lasting hair color.&amp;quot; 2. Washing your hair too often &amp;quot;Color&amp;#039;s worst enemy is water,&amp;quot; colorist Ruth Roche told Good Housekeeping. The chemicals in hair dye make your hair more vulnerable to water&amp;#039;s effects. This doesn&amp;#039;t mean you need to stop taking showers \u2014 just make simple tweaks to your routine, like avoiding excessive rinsing:&amp;quot;Once you&amp;#039;ve shampooed and conditioned, don&amp;#039;t tilt your head back and let the water just run over it for several minutes,&amp;quot; says Teca Gillespie, a scientist with P&amp;amp;amp;G. Instead of shampooing your hair every day, try using a dry shampoo at the roots to soak up oil. 3. Rinsing with hot water Adjust your water temperature to lukewarm or cold when rinsing. Hot water lifts the outer cuticle layer, which is one of the most common reasons that color fades, says Scrivo. The hotter the water, the quicker the color loss.

Not using a conditioner for color-treated hair Dyed hair is more likely to become dry and brittle, so treat it often with conditioners specifically formulated for color-treated hair. It helps create a protective barrier, which can prevent your dye from quickly washing out. Make sure to condition every time you shampoo, even if you have fine hair. &amp;quot;You really want to make sure you condition the longest part of your hair,&amp;quot; says Gillespie. &amp;quot;The tips can be years old and have the most damage, whereas the roots are only a couple of months old.&amp;quot; Try using a leave-in conditioner for even more of a moisture boost. 5. Drying roughly with a towel Scrubbing too hard can fade color and make the ends look dry, says Lisa Marie, VP of shows and education for Farouk Systems. Instead, gently blot your hair and let it air dry as much as possible. 6. Overusing your curling iron, flat iron, or blow-dryer Colored hair is more vulnerable to heat. To keep from frying out your hair, apply a heat protectant spray before using tools like your curling iron. RELATED: Subtle Hair-Color Changes That Make a Big Difference \u00BB 7. Forgetting the glossy factor Your hair may be a gorgeous new color, but has it lost its shine? Your hair&amp;#039;s protein layers (cuticles) reflect light and cause it to shine, but dye dulls this luster. To get that Kate Middleton-esque shine back, use an overnight hair repair treatment, spray-on gloss with a serum, shine spray, or an at-home glaze. And, again, cut back on the heat tools. 8. Over-exposing your hair to the sun If you plan on spending lots of time in the sun, wear a hat to keep your hair color from fading or lightening. 9. Re-dyeing unevenly When it&amp;#039;s time for a touch up, carefully apply the color on the roots only. Then, just before you rinse out the color, Estelle Baumhauer, the Color Director at eSalon, suggests an emulsion technique, which will revive the color on the ends and add body and shine. After you apply color to your roots, step into the shower and add a bit of water onto your hair, right on top of the color. Start massaging the color at your roots, similar to a shampooing motion. Thoroughly massage the color all the way down from roots to ends, adding more water as necessary. This whole process should take two minutes \u2014 just enough for a perfect refresher. Then proceed to rinse your hair. Photo credit: powerofforever/Getty Images NEXT: 7 Bad Habits That Are Ruining Your Hair \u00BB "^^<http://www.w3.org/2001/XMLSchema#string>
