How to Grow Out Hair Color Seamlessly

Cut your dead ends off first, as they are the most porous. “When your hair is porous, it can grab too much dye, which can look muddy or inky,” warns Brown. The best way to prevent this is to layer a warm hue (usually a deeper yellow or orange) before adding any dark tones over it. To maintain the color at home, swap in a weekly gloss. (Brown recommends dpHue’s Color Boosting Treatment.)

“To go back to blonde quickly, I would highlight the hair every few weeks. If you don’t mind taking your time (which is recommended to minimize damage), I would let the hair grow in and add highlights every couple of months until you reach your desired lightness,” says Brown. To ward off brassiness in-between appointments, use a purple or blue shampoo. Purple is best for lighter blondes; blue works for warmer, buttery blondes.

A combination of lowlights and gloss (in a slightly darker shade) will blend the colors so you get a more even grow out (read: less stripe-y). “I don’t like to take away highlights all at once because that can be too drastic of a change,” explains Brown. “If your highlights are pretty close to your natural hair color, even just a gloss can help blend the color,” she adds.

You need to strip the color out of your hair first (which can easily be done in the salon) before adding any additional color over it. Again, if you’re going back to brunette, it’s key to layer those warm tones first to get an even (and not inky) shade of brown throughout. And remember: Colored hair is weaker and more susceptible to breakage, so make use of a weekly conditioning treatment.

Stick with it. “Eighty percent of the women who tell me that they are going to go gray come back a few months later because they initially hate it,” explains Brown. The best way to grow out a single process (that is, when your hair is one shade) is to add lowlights. This will help blend in any lines of demarcation between your dyed hair and your natural roots. During this time, try parting your hair the opposite way. You may find that you have fewer grays in a different section,” advises Brown.
