Before we go a long into the processes about how to bleaching your hair, we'll learned a little bit about what is hair bleaching. Hair color is a result of pigmentation hair follicles. This happens because of two kinds of the melanin: eumelanin and pheomelanin. Put it simply, If there are more melanin present in the hair, the color will darken and if there's are less melanin, the hair color will be even lighter. Bleaching hair removal process is none other than the hair color of the hair stranded. However, how does bleach work? The ammonium persulfate or hydrogen peroxide is the main material found in hair bleach. They are also called an oxidant. These agents alter the composition of melanin in the hair by the oxidation. As a result of melanin turns white or colorless. Given below are tips on how to bleach your hair:
Things You Will Need 
- Bleaching powder
- Toner
- Hair color additive
- White creme developer
- Hair coloring brush
- Shampoo and deep conditioner
- Mixing bowls either in plastic or glass; no metal bowls
- Protective eye gear
- Shower cap
Step 1: Pour about three ounces of creme developer and two scoops of bleaching powder in a glass or plastic mixing bowl. Mix it well. 
Step 2: Now, part your hair into four sections. It is better to  start at the back and not at the roots because you would not like to  have lighter roots and darker ends.
Step 3: You can now apply bleach to your hair with the hair  coloring brush. Leave a gap of one and a half inches from the hair roots  and then apply it to the rest of your hair. Be careful not to massage  your scalp too much with it.
Step 4: Tie your hair underneath the shower cap. Keep it like  this for around sixty minutes but not more than that because there is  always a risk of chemical burns which may destroy your hair.
Step 5: The next step is to wash your hair with a good shampoo  which has PH neutralization properties. It will also help to stop  further acidic or basic chemical reactions that may occur in your scalp.  This step is very necessary because this will formally end the  bleaching process.
Step 6: If your hair does not turn out as desired, you can go for  a protein treatment and then for a deep conditioning. This will ensure  that your hair is moisturized well.
Step 7: Repeat the process after waiting for about a week. Your  hair color should become light yellowish. Two to three sittings are  enough for the process. Wait for at least a week between the treatments.
Step 8: Now, it is time to tone up your hair again to get the  desired shade you want, but it is recommended that you don't protein  treat or condition your hair at this stage. Along with the toner, mix 30  volume creme developer in a mixing bowl and add a few drops of hair  color additive depending on how golden or platinum you want your hair to  be.
Step 9: Let it set for 40 minutes or as given in the directions  for the toner; then wash, condition and dry. Look into the mirror and  voila! a perfect blond.
