So, Should You Dye Your Hair Dirty or Clean?

For starters, you need to assess the condition of your hair, decide which shade is best for you, and find the right formula—and that's before you even start the coloring process.

Coloring your hair at-home can be challenging, especially if you're doing it all on your own.

DO: Steer Clear of Permanent Color

Dying our hair is shifting the interior and the exterior of our strands, so the way we treat them is key to color preservation, vibrancy, and health. We put together a list of the 10 most common hair color myths and tapped expert colorists Ashley Pineda, Aspen Rae, and Kathy Debski to help us sort the facts from fiction when it comes to caring for dyed hair. As mentioned above, both experts say that hair color adheres better on clean strands as there is nothing blocking it from directly attaching. Yusef says that product buildup can prevent color from reaching the hair, and emphasizes that keeping your locks healthy will help prolong your new hue’s life. If you’re not sure whether you should wash your hair before the coloring process, it’s a common step to be confused about. In order to settle the debate, Bustle tapped two celebrity hairstylists — Yusef and co-founder of Good Dye Young Brian O’Connor — to break it all down.

"Buy more than one box of color—you don't want to be short on product in the middle of the process." While often we perceive it as an unwanted occurrence, it does help protect your hair and scalp. That’s why you don’t want to wash these oils out with a shampoo right before coloring. Truth be told, box dyes can actually set you up on a journey of hair damage, with more time and money ultimately being spent in the end. "Box dyes should be avoided in all circumstances," says Debski. "They contain high counts of metallic salts and other dyes," which can have an adverse effect on your strands, "especially if a client is wanting to eventually go lighter."

In general, people with oily hair may need to wash their hair more frequently than those with drier hair. People who use products in their hair may also need to wash their hair more regularly to remove residue. Contrary to popular belief, hair does not need daily cleaning. Some people may wash their hair daily, and others may be able to go a few days without washing their hair. Some people may need to wash their hair daily, while others wait several days or even weeks between washes.

By following these tips, you’ll be sure to get the best results from your hair color and keep it looking beautiful.

To achieve the perfect hair condition before coloring, professionals suggest that you skip shampooing at least 24 hours before the hair dye process.

Cutting your hair before you color will ensure you’re able to see the full effect of your color. Perm first to ensure that the perming process will not interfere with your newly applied color.

Use quality color products and protect your hair with a toning shampoo and conditioner system for long-lasting vibrancy. It’s important to dry wet hair before arriving at your next appointment, especially if you have darker tones.
