How many minutes to bleach women’s hair?

For light brown hair, bleaching is not a big deal. However, if your hair is dark brown or black, getting blonde or white can be a challenge. Even so, with just a little toner and bleach, you can bleach your hair the way you want.


Part 1 Part 1 of 3: Prepare for great results

  1. first

    Check that the hair is strong enough to withstand the bleach. There is no way to avoid serious damage to the hair exposed to bleach. Many stylists do not bleach colored or treated hair. You should consult a hairdresser first to avoid damage to your hair.[1]

  2. 2

    Set aside an appropriate amount of time. To bleach black hair to blonde, especially metallic blonde or white, you need to repeat the bleaching process several times, several days apart.[2]
  3. 3

    Choose the right bleach. There are many options for bleaching your hair and you need to choose the right bleach for your hair color.

    • Look for a hair bleaching kit, which includes a hair color remover powder and a peroxide solution. This is a strong formula suitable for dark hair.
    • Peroxide comes in several strengths, from 10 to 40. Note that strength 40 is too strong for normal hair bleaching as it can cause scalp burns. Peroxide intensity 40 is only used to apply to the ends of black hair, which is not in contact with the scalp. Strength 30 peroxide will work faster than strength 20 or 10.[3]
  4. 4

    Test bleach on a strand of hair before you begin. This step is very important because it helps you know how long to keep the bleach in your hair to achieve the desired hair color. Always carefully read and follow the manufacturer’s instructions (instructions included with the hair color remover kit) on how to test on a strand of hair. In general, the steps include:

    • Separate a few strands of hair from the back of your head in an inconspicuous spot. Tie strands of hair together with a string or use tape to stick one end of the strand together.
    • Mix a small amount of hair color remover powder with the peroxide solution according to the manufacturer’s instructions.
    • Dip the strand of hair into the bleach mixture until it is completely wet.
    • Set a clock or monitor the time during the hair dye test.
    • Check your hair color every 5 minutes using an old cloth to wipe off the bleach.
    • Apply bleach to your hair again and repeat the process until you get the color you want. At this point, you will know how long to keep the bleach in your hair.[4]
  5. 5

    Soak your hair in melted coconut oil and leave it overnight. Before bleaching your hair, you need to massage unrefined coconut oil into your hair and oily skin. This step helps to protect the hair from excessive damage during the bleaching process. Leave the coconut oil on your hair for 14 hours for best results.[5]

Part 2 Part 2 of 3: Hair bleaching

  1. first

    If your hair is long, you need to divide it into 4 sections. Use the sharp end of the hair dye comb to part your hair into 2 sections from the center of the forehead to the nape of the neck. Next, divide each section of hair into 2 more sections from the tip of the ear to the top of the head.

    • You need to use pins or clips (not made of metal) to secure each section of hair. Make sure the pins or clips don’t react with the chemicals in the bleach.[6]
  2. 2

    Protect skin, eyes and clothing. You need to take basic precautions when using bleach. Wear nylon gloves and protect your eyes by wearing goggles. In addition, you should also wear old clothes and spread something on the floor to prevent the bleach from dripping.

    • You can also apply a thin layer of moisturizing wax to your forehead, ears, and neck. While it’s not as necessary to avoid staining as it is to dye your hair, a moisturizing wax can protect your skin from irritation if the bleach comes into contact with your forehead, ears, and neck.
  3. 3

    Mix bleach. Mix hair color remover powder with a 1:1 peroxide solution in a non-metallic mixing bowl. Mix until the mixture thickens like a cream.

  4. 4

    Apply the mixture. Use a hair dye comb to apply the mixture, starting from the hair about 1cm away from the scalp.

    • First, apply the mixture to the thin section of hair at the back of your head, making sure your hair is completely covered with bleach before moving on to the next section. Use a clip to secure the section of hair that has just been bleached before moving on to another section.
    • Apply bleach to the back two sections, then the front two sections.
    • Apply bleach in the direction of hair growth, from the roots to the ends.
    • Apply the bleach as quickly as possible because the hair needs to be soaked in the bleach for the same amount of time for an even color. You can use a different strength dye solution to achieve this result, for example using strength 30 for the front hair and strength 20 for the back hair.
    • Wear a hair cap after your hair is completely covered with bleach.
  5. 5

    Monitor the process. Test every 10 minutes until desired hair color is achieved.

    • Test your hair color by wiping the bleach on a small section of hair with an old cloth. If you want to continue, you need to reapply bleach to this section of hair.
    • You can set the timer to alarm every 10 minutes to ensure uniformity.
  6. 6

    Consider heating with a dryer to speed up the bleaching process. However, you should be aware that any heat-generating process increases the risk of damage, so you should avoid it if you’re not in a hurry.

    • This is not recommended if this is your first time bleaching your hair as you need to find out how long the dyeing process will take. If you want to bleach your hair again, you can speed up the process with heat. [7]
  7. 7

    After 10-20 minutes, apply bleach to the roots. Thanks to the heat from the scalp, the hair at the roots is bleached faster. If you want to bleach your roots, it’s best to apply bleach at the end of the process. Use the sectioning technique as described above, but this time just apply the bleach mixture to the roots.[8]

  8. 8

    Rinse off the bleach. After the hair has reached a light blonde color or has expired the manufacturer’s recommended retention time, you need to rinse the bleach with warm water.

    • Use a small amount of shampoo, preferably a shampoo specifically designed for freshly bleached hair. For example, a shampoo containing a purple toner will help remove the brassy or yellow color from your hair.[9]
    • Use a towel to dry your hair and style as usual. If possible, you should avoid heat styling because heat increases damage and stress on your hair.
  9. 9

    Evaluate the results after the hair is dry. Only when your hair is completely dry can you really see the results of the bleaching process. Remember, it can take at least 2-3 bleaching sessions within a month to turn black hair into light blonde or white.

  10. ten

    Let your hair rest for 2-3 weeks between bleaching. Bleaching is a harmful process for hair. Therefore, you need to avoid continuing to bleach the color even if you are not satisfied with the results. Instead, you should use a toner after each bleaching (see instructions below) to balance the color of your hair as your hair gradually turns from black to light blonde. [10]

Part 3 Part 3 of 3: Apply toner to your hair

  1. first

    Choose a toner (product that balances hair tones). This is an important step for beautiful hair and balanced hair color. Bleaching removes the pigment from the hair and eventually leaves a bit of yellow – the natural color of the hair’s keratin or protein.[11]
  2. 2

    Prepare and apply toner. Here are general guidelines, but be sure to follow the manufacturer’s instructions:

    • Mix toner with 10 or 20 strength dye solution in a ratio of 1:2. If your hair is dark, you should consider using a strength 40 solution. However, keep in mind that a strength 40 solution is very strong and can cause serious burns if it touches the skin. Seek medical attention if chemical burns occur.
    • Apply toner evenly from roots to ends, using the same sectioning technique as when bleaching hair according to the instructions above.
    • Many toners only take 10 minutes to work, so you need to apply as quickly as possible and monitor the time closely. [15]
    • Test the process every 5-10 minutes using a single strand test like the bleaching instructions above.
    • Be careful not to over-balance the white hair color to avoid a yellowish or gray tint.
  3. 3

    Head washing. Use shampoo and conditioner, then style your hair as usual.

    • Be sure to throw away any unused bleach and color balancer mixture when you finish bleaching your hair.


  • Do not leave the bleach on your hair longer than it has reached a light blonde color.
  • If you have short hair (shoulder length or shorter), you should consider dyeing highlights instead of bleaching. This way, you can avoid the risk of burning your scalp.
  • It is best to bleach your hair before washing it.
  • Having someone to help is better, especially when bleaching your hair for the first time. You should consider asking someone to help you make sure the bleach is evenly applied to your hair.
  • Colored hair conditioners, color balancing shampoos, and color care shampoos can help balance blond hair and give it shine. [16]
  • Deeply moisturizes hair between bleaching to restore hair’s natural oils and proteins.
  • Wash your hair as little as possible between bleaching sessions, as washing will strip away the protective oils and keep it soft. [17]
  • Limit heat styling (drying, straightening, curling) if possible, as heat will put extra stress on already weakened hair.
  • Incubating coconut oil or argan oil every two weeks is a great way to maintain hair color after bleaching.
  • Do not use direct heat when bleaching hair color. Once it dries, the bleach will stop working. You can use a plastic bag, a hair cap, or even foil to cover your hair. THEN, turn the dryer on LOW to speed up the bleaching process while the hair is covered.


  • DO NOT use bleach to remove eyebrows or eyelashes.
  • Dye auxiliaries 40 is extremely strong, so use only when needed and absolutely do not mix with toner.
  • Do not apply bleach directly to the scalp.
  • Carefully read and follow the instructions included in the product packaging.
  • A complete hair color bleaching within a day is not recommended as it is very harmful to the hair.
  • If you start to experience burning or irritation while bleaching your hair, you should wash your hair immediately and consult your doctor.
