The Ultra Cool Booster is perfect for those who want maximum neutralization while bleaching. Here's what you need to know:

• Additive for extra coolness when bleaching
• Specially for natural bases (levels 3 to 7)
• Reduces warm undertones while lightening
• To be used with Lightener 9+ (white & blue)
• Works on medium blonde to dark hair.
• Vegan formula
  
  

Mix in the ratio 1:10:20 :

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

Apply the mixture to dry, unwashed hair and leave it on for 20 to 50 minutes . No additional heat is needed. Monitor 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, so you get a pure, bright blonde color – even on darker or natural hair colors.

This booster contains a powerful, neutralizing formula specifically designed for use with bleaching products. It targets the underlying pigments and prevents unwanted heat buildup during the lightening process.
