To get platinum blond hair, use hair bleach to remove the pigmentation. Follow up with a deep conditioner, then use a toning color to cancel out yellow undertones. Use toning shampoo to keep your hair platinum for as long as possible.
- Prepare for the coloring process
Divide the hair into four even sections. Cover your clothes with an old towel to protect them from drips. Put on protective gloves.
- Mix the bleach
Mix equal parts bleach powder and peroxide developer. For light blond hair, a 20-volume developer is sufficient. For dark blond hair, choose 30-volume developer. For all other hair shades, choose 40-volume developer. Mix the ingredients together in a plastic bowl with a tint brush until the mixture is smooth.
- Apply the bleach
The hair near the scalp and at the ends processes more quickly, so apply the bleach starting 1 inch away from the scalp and ending 1 to 2 inches from the ends. Apply the bleach to skinny sections, working it into the strand to ensure even distribution.
- Finish applying the bleach
Once the mid-shaft has started to lighten, go back and apply the bleach near the scalp. As soon as you have finished with the scalp, pull the bleach through to the ends.
- Process the bleach
Cover the hair with a plastic cap. Process the hair in five-minute increments, checking the color after each increment for the desired level of lightness. Keep processing the hair until it is pale and light.
- Condition the hair
Rinse out the bleach until the water runs clear. Apply a deep conditioner made for strengthening the hair, and leave it in for a minimum of five minutes. Rinse with cool water.
- Apply the toner
Mix the toning color according to manufacturer's instructions. Look for purple-based toner to cancel out the pale yellow of the hair. Process in five-minute increments, checking for the desired color. Rinse out immediately once your desired results are achieved.
- Use toning shampoo
Use a purple-toned shampoo to wash the hair after bleaching. Use this shampoo regularly to keep hair platinum.
