Light Blonde Flashes
A: I never advocate attempting to lighten your hair more than 3-4 levels without professional assistance. The hair could be seriously damaged by trying to remove too much of the natural pigment from the hair. Your best bet is to consult a professional colorist about having the blonde highlights put in your hair safely.
It is also important to closely monitor the progress of the lightening. Depending on the condition and texture of your hair, you could see rapid lightening and will need to be ready to rinse the hair before the lightening progresses too far.
It is also possible that the lightening process will be slow. In this case, you should remember that applying heat to the bleach-covered hair speeds up the bleaching process. It is also important to remember that unlike color application, bleach does not lose its potency. So long as it remains wet, it will work. Because of this, you should cover the hair with a plastic cap to retain the moisture and ensure even lightening.
When it comes to removing the bleach, be sure to rinse the hair with cool water and shampoo it with a moisture-rich shampoo. The cool water will stop the lightening process and the shampoo will remove the bleach.
Starting with black hair, you may experience unexpected tones in the lightened hair depending on the contributing pigments of your natural hair color. The most common tones are orange tones, yellow tones and greenish tones.
