How to Bleach Your Hair at Home? – Step by Step Guide

Change is constant and inevitable. Some people embrace it while others resist it. Although, some changes can be voluntary and extreme, if you wish to bleach your hair blonde, here is a step by step guide of how to go about it!

You will need:

  • Bleaching Powder
  • Developer
  • A hair-dye brush
  • A plastic or glass bowl (do not use steel)
  • Gloves
  • An old tee-shirt
  • A few rubber-bands
  • A few clips (to help make segments)
  • Mild Shampoo
  • Deep Nourishment Conditioner
  • A Thin Toothed Comb
  • Cling Film

Before you start there are a few things that you need to be careful about. Firstly, to avoid getting your clothes dirty, put on an old tee- shirt, since once there is bleach on your clothes, there is no turning back. Secondly, make sure to conduct a patch test. A patch test is when you take a small segment of your skin at the back of your head (so that not ordinarily visible) to check for allergies if any. Thirdly, it is important to bleach unprocessed hair since there will be less chance for damage. Fourthly, it is important to apply bleach to hair that has not been washed for at least 3-4 days to retain its natural oils to protect it from becoming brittle and eventually breaking.  

Note: Bleach tends to sting a little. This is normal. But if the sting starts to feel like a burning sensation, wash off the bleach immediately.

The duration you leave the bleach on for decides the effect it will have on your hair. If you have dark hair, then the bleach should be kept on for at least 40 minutes to see positive results. Keep reducing 5 minutes of time depending on the colour of your hair and the colour you desire. Under no circumstances should you keep the bleach on for more than 40 minutes in one sitting. Another sitting is recommended if the desired shade has not been achieved. Remember these sittings need to be spaced out with a gap of at least 2 weeks so that the hair is given some time to regain its natural oils.  

Read all the instructions on all products properly so that you can test yourself for allergies as provided if any, as given on different products.

The following steps will help you bleach your hair perfectly.

Step 1: Collect all your supplies:

Get everything you need together. You can also get a friend or two to help you out.

Step 2: Prepare your hair:

Prepare Hair

Do not wash your hair for 3-4 days before you plan to bleach them. So that the natural oils can help repair any damage caused.

To start applying the bleach you need to part your hair from the middle and tie a rubber-band on the hair on one side so that they do not get tangled with the hair on the other.

Step 3: Prepare the bleach: Time:

Put gloves on and to a bowl add the bleaching powder. Now add the developer, enough to make a paste like consistency. Mix this well. You should continue mixing developer till a paste like consistency is achieved.

Step 4: Get Bleaching: Time: 

Wear an old tee-shirt. Protect your neck with cling film. In the parted hair using a brush start applying the bleach from the roots. After the first layer of hair has been sufficiently covered with the paste, pick up another segment of hair and from the side which is not tied in a pony-tail and lay it over the first layer of hair. Now, apply another coat of bleach paste. Keep repeating these steps till one side is completely covered in the bleach.

Now, part your hair along the centre again and repeat these steps on the other side.

After completing these steps only the back of your head should be left to bleach.

To bleach the back of the head start by taking segments of hair horizontally from the back of the crown of your head. Bleach by layering the hair and covering them in bleach properly. Make sure that the segments of hair that you take have only small chunks of hair at one time. This will ensure even bleaching.

Step 5: Cling Film it:

After making sure that the bleach is applied evenly on all segments of hair, comb it with a thin tooth comb and tie it in a bun. Now, use a cling film to cover it up. This will ensure that the bleach does not discolour anything else.

Cling Film it

The cling film will also keep the hair moist and warm. This helps the bleach work its magic faster. When the hair is moist and warm it absorbs more chemicals to reduce the natural colour of the hair.

When you bleach your hair there is removal of a pigment from the hair. This pigment gives colour to the hair it is called melanin. Bleach reduces this pigment and makes it light and gives it a blonde colour.

Step 6: Rinse it off:

After 30 minutes of keeping the bleach on take a small segment of hair and wash it off to check the colour. If you are satisfied you can go ahead and wash the rest of it off. If not apply the bleach back to the hair which you washed and wait for another 10 minutes.

After 10 more minutes have passed, whatever may be the colour, thoroughly wash off your hair with mildly hot water. Once the bleach is completely off, rinse your hair with a mild shampoo, twice.

Now, apply a conditioner to the hair to restore its natural feel. Leave this conditioner on for 10 minutes before washing it off.

Step 7: Let your hair dry Time:

Do not use a hair dryer to dry your hair, let them dry naturally. The blow dryer can damage your hair even further. The chemicals in the bleach already cause a lot of damage to the hair, using hair dryer the very first time can increase the chances of split ends.

Only after your hair has dried completely will you be able to tell the actual colour achieved. If you are not satisfied with the colour you can re-bleach your hair after a period of 2 weeks has passed.


  • Always wear gloves before you start to apply bleach to your hair.
  • Do not wash hair 3-4 days before you’re to bleach your hair.
  • Do not apply bleach to already processed hair. This will cause further damage.
  • Do not use hair dryer right after washing bleached hair.
  • Do not let the bleach touch any scar or wound.
  • Do not let the bleach enter the eye.

Care for hair after bleaching:

  • The night after bleaching your hair to restore its natural oils you can apply a hair mask. For this hair mask, you need to apply coconut oil to damp hair. Just like damp hair absorb chemical fast they also absorb nutrients at the same rate. Hence it is important to oil them.
  • Make sure to not use any other colouring or decolouring products for at least 2 weeks after bleaching.
  • Do not use a hair dryer very often once your hair is bleached. Use it only in emergencies. This is will help keep away split ends for a longer time.
  • If you use a hair dryer or a hair straighter on a regular basis then for all practical purposes invest in a good heat resistant hair serum which can be applied before drying or straightening. This will minimise the damage to the hair.
  • Bleached hair tends to get tangled more often, since the texture of the hair changes once you bleach them. To get rid of these knots use a wide-toothed comb to ensure minimum breakage.
  • You can also consider getting a professional hair spa at a salon to restore its natural texture. Spas which use the chemical keratin are usually helpful in increasing the elasticity of the hair making it look healthy and beautiful.
