Getting rid of bleach-blond streaks involves coloring hair back to its natural shade in a three-step process: filling the hair, applying the target shade and sealing with a color gloss. The process takes around 1.5 hours and requires semi-permanent hair color, permanent hair color, chemical color gloss, gloves and a color bottle.
- Mix the filler
Bleached hair is stripped of all color. Red is the last to go during the bleaching process, which is the source of brassiness, so it is the hue needed to fill the hair for natural-looking color. Mix a semi-permanent hair dye with red-gold tones at the target level of darkness.
- Apply the filler
Use a color bottle to target only the streaks. While wearing gloves, work the color into the hair. Allow the color to process according to the instructions on the box.
- Rinse out the dye
Use cool water to rinse out the dye until the water runs clear. Do not shampoo. Towel dry the hair.
- Apply permanent dye
Choose a warm shade of dye to avoid dull tones in the hair. Mix the dye according to the instructions on the box. Using a color bottle and gloves, apply the dye only to the streaks and process as directed. Rinse the hair.
- Apply a color gloss
Bleached hair typically loses its luster. Likewise, the streaks are more likely to fade to light again. To slow down this process, apply a chemical color gloss over all the hair. This returns the hair's luster and seals in the dye.
