If you’re buying based on the image on the front of the box, look for one that’s slightly lighter than what you want. [3] X Research source
Use a dark towel to hide any stains from the dye.
Some kits will also include a conditioning or moisturizing treatment.
Get as close as you can to the base of the roots without touching the scalp. If the color matches your natural roots, try to blend it into the roots so you don’t have to worry as much about grow-out. Color-matching can be very difficult, though, so unless you have a lot of experience with coloring your hair, you may want to just dye your whole head. [7] X Research source
After rinsing, apply a conditioner for color-treated hair, following the manufacturer’s directions. This will help seal in your color.
Color layering can be quite tricky, so if this is your first time using a tinted protein filler, you may want to consult with a professional colorist before you start.
You should also put on a pair of latex gloves before you begin to avoid tinting your skin.
To avoid any contamination, make sure to use a clean spray bottle for the color protein filler.
You only need to apply the filler to any bleached or dyed hair! Don’t worry about your natural roots, since they aren’t brittle or porous from being processed. [12] X Research source
Make sure to use a plastic wide-toothed comb that you don’t mind getting filler on.
This may mean skipping a workout or two in order to avoid the need to wash your hair. You can also wear a shower cap to keep your hair dry in the shower.
If your strands get greasy between washes, try using a dry shampoo.
If you have to use hot tools, make sure to spray on a heat protectant product first and use either the lowest heat or cool blast setting. You should especially avoid using hot styling tools in conjunction with heavy styling products, such as gels, volumizers, hairsprays, and mousses.
Look for a moisturizing mask that’s specifically formulated for colored hair. This is especially important if your hairstyling requires heat tools.
