Among the common home treatments is the bleaching bath. The most common question regarding it is, ”how do I bleach my hair? I’ve never done it, and I’m afraid of ruining it”.

Understanding that bleaching is an aggressive process, all the steps explained below must be done with patience and care, following each one to the letter.


What is a hair bleaching bath?

You probably already know that two very strong chemicals are mixed in the bleaching process, such as peroxide and bleach. These chemicals seek to lighten the hair tone by removing its natural pigments.

Keep in mind that these chemicals tend to be aggressive with the hair strand to degenerate the natural melanin pigments. So post bleaching care is a must to make your hair shine bright.

Now, let’s start with the whole guide.

The bleaching bath can be done in 5 simple steps: mix the developer, add shampoo, apply, let it sit, and finally wash.

Compared to conventional bleaching, bleaching baths are slightly less aggressive, with effective results while protecting your hair.

Things you will need to bleach bath your hair

  • A bowl
  • Hydrogen peroxide (developer)

  • Shampoo (remember to avoid these bad ingredients)
  • Conditioner (if you have thin hair)
  • Shower cap
  • A towel or old clothes for your shoulders

What are the steps to bleach bath your hair at home?

Mix the developer

Mix 2 tablespoons developer and 1 bleaching powder. Stir together in a bowl to form a thick paste that is easy to apply by hand. If you are dark-haired, just add one more bleach tablespoon.

  • If you have thinner hair, use 10-volume hydrogen peroxide, but if you have a stronger one, choose a 20-volume. 10 being the weakest and 40 the strongest.
  • If it is the first time, start with 10.
  • You can buy bleaching powder in the hair care section of hypermarkets, no need for a professional brand.

Add shampoo

To the previously made mixture, now add shampoo. Use the same amount as if you were washing your hair.

  • If your hair tends to dry out, you can also add a little conditioner.
  • Avoid using an anti-residue or toning shampoo as it can damage your hair.

Apply the mix

  • Wear gloves since you are handling chemicals and the hand’s skin is fragile.
  • Place a towel on your shoulders to protect you from the chemicals and your clothes.

First, we recommend wetting your hair a little and separating it into sections for easy application and more effective bleaching. Do this in 7 sections: top, left side, right side, crown, left nape, right nape, and back.

Finally, start the scalp application and work your way down to the roots. Then start massaging the mixture, just as you wash your hair.

Let it stand

  • If you have thick, long hair, leave the cap on for up to 45 minutes.
  • If you don’t have a shower cap, you can also tie your hair up in a bun.

Wear a shower cap for up to 30 minutes. Cover your hair, so the bleach mixture doesn’t drip everywhere.

Pull out a small strand of hair and check the color every 5 to 10 minutes. Remove the shower cap after 30 minutes or when you get the desired tone.

How long the mixture should stay on your hair also depends on whether it is your first time or not. If you have bleached your hair before, 10 minutes will be fine, but if it is your first time or if you’re dark-haired, 30 to 40 minutes may be necessary.


It’s time to rinse your hair! We recommend rinsing your hair with warm water, not too hot or too cold.

Warm water helps to completely remove the paste residue. Be sure to wash your hair thoroughly but gently. Rough massages can break it.

How to care for your hair after bleaching?

After bleaching, intensive and constant care is decisive to avoid the abrasive consequences of the process.

Always moisturize your hair.

Use cream and products rich in vitamin B5 at least twice a week. Vitamin B5 is an essential ingredient for all repair processes, from scarring to burns, including hair recovery.

Treat it with kindness.

Treat your hair with kindness. Massage gently with the fingertips during washing, in a circular motion, and without too much pressure.

You should also comb carefully and slowly to prevent breakage, also avoid ironing at too high a temperature.

Cut it frequently.

To keep it strong and shiny, try to cut it every 2 months. It doesn’t have to be too much, but just a couple of centimeters. Constant trimming strengthens the hair strand and promotes its growth.

Don’t wash it so often.

The bleaching process strips the hair of moisture, leaving it dry and prone to breakage. Frequent washing can make your hair even drier and more prone to breakage.

For example, imagine washing your hands several times a day with soap and water. Gradually the skin dries out and cracks. The same happens when you wash your hair often.

If you have oily hair, try products full of moisturizing factors and homemade masks, and natural ingredients that can give your hair the nourishment it needs.


The bleaching bath is a good alternative without the irritating effects of conventional bleaching. It is fast, simple, and less aggressive. But this fact does not diminish its aggressiveness, as it also damages the hair since the basis of bleaching is to degrade its natural pigments.

Consistent care will keep your hair looking soft, shiny, and strong even after bleaching. If you follow our recommendations carefully, you will see that your hair will achieve the desired tone and that amazing healthy look.
