Depending on your starting level, health of your hair, processing time, and method of application, you can get up to 7 levels of lift. To get a clear understanding of how your hair will lift, we suggest doing a strand test prior to full application.
Mix 2 teaspoons of developer with 1 teaspoon of bleach powder using non-metal utensils.
Wearing gloves, apply to a 1/8 inch section anywhere from the back of your ear to the nape of the neck. Let strand process from 15-40 minutes, checking progress every 5-10 minutes.
Once the desired level of lift is achieved, thoroughly rinse strand.
If you are happy with the results, proceed with full bleach application.
