Mix in the ratio 1:10:20:

• 1 part Ultra Cool Booster
  
  
• 10 parts Indola Lightener 9+
  
  
• 20 parts Cream Developer (2%, 6%, or 9%)
  
  

Apply the mixture to dry, unwashed hair and leave it 20 to 50 minutes processing. No extra heat needed. Check the process until the desired result is achieved.

The Indola Blonde Expert Ultra Cool Booster makes your lightening even cooler and more even. Warm undertones are neutralized during the process, giving you a pure, bright blonde color – even on darker or natural hair colors.
