L'Oréal Professionnel Diactivateur 6 Vol Developer – Gentle Toner Activator

This is the gentlest developer in the Diactivateur range, formulated for pure deposit services on pre-lightened or sensitized hair. It activates Dia Light and Dia Color with minimal cuticle opening, preserving the structural integrity of the hair while delivering maximum shine, tone deposit, and transparent color results. Ideal for gloss services, tone refreshing, and Milkshake blonde formulas.

Professional Benefits

• Lowest-volume developer for deposit-only, zero-lift results
  
• Maximizes shine and tonal transparency on bleached or highlighted hair
  
• Gentle on sensitized, previously lightened, or fine hair
  
• Ideal for glossing services and in-salon treatment-style color
  
• Ensures the most luminous, glass-like finish from Dia Light Milkshake shades
  
• Minimizes processing risk on fragile or over-processed hair

How to Use

1. Measure the appropriate amount of Diactivateur 6 Vol developer
   
2. Mix with Dia Light or Dia Color in a 1:1.5 ratio (color to developer)
   
3. Apply evenly to clean, towel-dried hair
   
4. Process for 15 to 20 minutes at room temperature
   
5. Rinse, shampoo gently, and finish with a color-seal conditioner

Pro tip: For Milkshake blonde toning or gloss services on freshly bleached hair, 6 Vol is the right choice. The lower volume protects an already compromised cuticle while still activating the pigment for bright, clean results.
