How To Bleach Your Hair

Coloring hair to make a change can be fun, but if you want to be dramatic, you will have to learn how to bleach your hair. When you add bleach to your hair, it will make it lighter depending on the brand you use, how long it stays in, and what color your hair was to begin with.  Bleach is the only way to go from black to blonde overnight.

  • You will need:
  • A plastic mixing bowl
  • Hair bleach powder
  • 30 or 40 volume developer
  • Gloves
  • Tint brush
  • Plastic cap
  • At least four hair clips
  • Junk shirt or towel to protect clothes
  • Shampoo and moisture rich conditioner
  1. Gather all the items you will need to bleach your hair. A mixing bowl made for dying mixtures is preferred; you do not want to use a bowl you use to eat. You can buy one from a beauty store along with all of the other items you need. Also, make sure you choose the correct developer. Use a 30-volume developer if you are going from a warm brown to blonde, 40 if you are darker.
  2. Place a junk towel over your clothes or wear an old shirt. Bleach will stain clothes immediately. It is also important to protect any other surfaces that you do not want damaged by bleach. This includes the bathroom counter, sink, floor, and any towels or clothes in your vicinity.
  3. Put the gloves on and start mixing. Pour the bleach powder into the bowl. Do not inhale the powder. Pour the 30 or 40 volume developer in with the bleach. Use four ounces of developer per packet of bleach. You may need additional packets to bleach your hair if longer than shoulder length or very thick. Use the tint brush to stir the bleach and developer mixture.
  4. Section your hair using the end of the tint brush. Usually four sections are easy enough to deal with when you bleach your hair. Secure each section that you are not working on with a hair clip. An easy way to section hair is to have a vertical part down the middle and then part them horizontally using the tips of the ears as a starting point.
  5. Start adding the bleach to your hair. If your hair is natural, start from the roots to the tips. You will need to place the bleach as fast as possible to keep the hair evenly saturated. If you dye your hair and the roots are lighter, start from the ends and work your way to the roots. You always want to bleach the darkest area first to keep your hair color even. When your hair is saturated, put the cap on to help develop your hair.
  6. Time the bleach. How long you keep it in depends on what color your hair is. If you are a blonde going lighter, only keep the dye in for 15 to 30 minutes. Light brown hair should be bleached for 25 to 35 minutes, with a medium brown lasting from 35 to 45 minutes. Dark brown or black hair needs at least 45 minutes to an hour for the bleach to lighten it. You should always take a peak under the cap at least every ten minutes to see your progress.
  7. Rinse the bleach out of your hair. Be careful to not get any bleach into your eyes. Shampoo and condition your hair using a moisture rich conditioner. Let your hair dry naturally. Expect your hair to feel somewhat rubbery and brittle. This is completely normal when bleaching hair.


  • Bleach can irritate your eyes and skin, be careful when you bleach your hair.
  • Bleach strips the natural oils from your hair making it brittle. This can cause your hair to break easily or have split ends.
  • Leaving the bleach in too long will damage your hair. Consult a professional of you are unsure of how much bleach to use or how long to leave it in.
