How to Darken Hair After Bleaching

Updated February 21, 2017

Bleaching is a process in which some form of lightening product is applied to hair. The most extreme cases of this process can cause hair to become almost white. If you don't like the way your hair looks after you have bleached it, however, you can attempt to change it to a more natural colour. Darkening your hair after the bleaching process is similar to colouring your hair normally, but with a few extra risks.

Choose a hair dye. Pay special note to the base colour of the dye and make sure it matches the base colour of the bleach, which is yellow. If you choose a hair dye with too strong a red or blue base colour, you can cause your hair to take on a green or orange tint.

Wash your hair before you start the dyeing process. Use a good shampoo to get out any pollutants. Do not use anything that contains conditioner. Make sure your hair is dry before you start dyeing.

Place a layer of petroleum jelly along your scalp line to keep your skin free from the dye. If you are not careful, the dye will colour your skin as well.

Mix the two dying agents that come with the dye kit in the supplied applicator bottle while wearing the protective gloves. Shake the dye components for approximately 15 seconds.

Begin at the hair line at the base of your neck and apply the colour to your hair. From there, colour the back of your head, then the sides, ending with the top.

Work the dye into your hair by rubbing it in as you would shampoo. Make sure you are wearing your protective gloves. Wipe up any dye that gets on your skin immediately with the towel. Let the dye set on your hair for 20 minutes.

Rinse your hair while wearing the gloves to get the excess dye out. Once rinsed, re-shampoo your hair.


If not done correctly, bleaching can seriously damage your hair. If your hair is damaged and you dye it, it may cause your hair to fall out. See a hair professional to minimise the damage from this process.
