8 Things You Should Avoid When Dyeing Your Hair at Home

Although many hairstylists advise against dyeing your hair at home, it can sometimes be the most practical choice. For instance, professional hair coloring might be out of your price range, but you still need to cover up those gray strands. Or maybe your colorist is unavailable on vacation. You could also be in need of a root touch-up and haven’t yet found a new colorist after parting ways with the old one.

If you opt to color your hair at home, it’s important to do it right to get the best results. Here are some typical mistakes to watch out for the next time you attempt a DIY hair dye job.

Always Read the Instructions on the Box

While many of us often skip the instructions for gadgets like toasters and microwaves, it's essential not to overlook this step when it comes to your hair dye. Knowing how to mix the dye and how long to leave it on is vital for getting the best results.

Stick to One Brand (If You're Happy With the Results)

"Avoid switching to a different brand of box dye if you're happy with the results," advises celebrity hairstylist Anthony Pazos. Sticking to the same brand ensures you get consistent hair color. If your preferred brand is out of stock at the local store, it’s better to go to a different store or keep an extra box on hand for future use.

Always Use Two Mirrors When Applying Color

Hairstylist Brittany Gharring recommends using two mirrors when coloring your hair on your own. "Coloring the back of your head can be challenging. Use a handheld mirror to check your progress in the bathroom mirror as you apply the color to ensure you don't miss any spots," she advises.

Always Buy More Than One Bottle of Color

For long or thick hair, this is a must. Grab an extra box. "You can never predict how porous your hair will be, and most color tubes are designed for shorter, thinner hair, so it's best to plan ahead," advises Gharring.

Don't Forget to Shield Your Skin

Protecting your skin while dyeing your hair is simple but important. "There's nothing worse than having noticeable streaks of color on your forehead," says Gharring. "To avoid this, apply a thin line of chapstick along your hairline and around your ears," she suggests.

Avoid Rinsing With Hot Water

You may be tempted to rinse with hot water because it feels more pleasant, but this isn't a good idea. "Hot water lifts the outer layer of hair color, causing it to fade more quickly," says celebrity hairstylist Cody Renegar. "Use cold water instead to help seal the cuticle and lock in the color."

Skip the Shampoo the Following Day

Do you wash your hair every day? If so, this might be tough, but it's best to refrain from washing your hair for at least a day or two. Renegar advises waiting 48 to 72 hours before shampooing. "This allows the cuticle to fully close and the color to set properly."

Steer Clear of Hot Tools After Dyeing Your Hair

While professionals might use hot tools to style your hair after coloring, it's better to wait a few days before reaching for that flat iron or curling wand. "Extra heat from styling tools can not only fade your color but also make your chemically treated hair more brittle and dry. You can use heat tools, but I wouldn’t recommend using them right after dyeing your hair, and definitely not frequently. If you must use them, always apply a heat protectant," says Renegar.
