How to bleach hair with peroxide & ammonia

Updated July 20, 2017

Having hair bleached at a salon can cost hundreds of dollars in metropolitan areas. Fortunately for the fashionista and city-goer, there is a more cost-effective solution to bleaching hair. There are many home recipes on how to bleach hair cheaply with peroxide and ammonia. However the method varies, the two main components are the backbone to this common do-it-yourself hair-care project.

Measure 1/2 cup of hydrogen peroxide into a bowl to make a bleaching paste that will effectively lighten hair.

Add 2 tsp of household ammonia. Stir well.

Add pure soap flakes until a thick consistency is achieved.

Spread a thick layer of the bleaching paste throughout your hair, whether it be on the body or head. Let it sit for 15 to 20 minutes.

Rinse the mixture out of your hair with cool water.

Repeat this treatment until the desired colour is reached, bleaching your hair no more than twice a day. After the colour is achieved, reduce the bleaching schedule to once a month.

For a prettier smelling and looking bleach paste, add 14.2gr. of soy butter, 14.8ml. of rose oil, 1 cup of distilled water and 1/2 tsp of borax to a glass bowl, then microwave it on high for three minutes or until the ingredients melt together.

Stir in 1/2 cup of hydrogen peroxide and 2 tsp of household ammonia. The mixture will thicken.

Pour the warm paste into a glass jar, and let it sit uncovered until it drops to room temperature. Then, spread a thick layer of the bleaching paste throughout your hair, and let it sit for 15 to 20 minutes. Afterward, rinse the mixture out with cool water.


Bleaching hair is a tricky process that can cause significant hair damage. Consult a certified beautician before proceeding with at-home hair bleaching.


Wear safety equipment when working with chemicals. Conduct a skin test at first to make sure the method you have chosen will not cause an allergic reaction.
