Intercosmo Voilà 3C Intense 60ml in shade 12.10 Ash Super Blonde is a salon-grade permanent hair colourant from Italian professional brand Intercosmo. The 12.10 shade is one of the lightest in the range — a high-lift super blonde with cool ash-toned reflects, designed to lift natural light bases into platinum or Scandinavian-blonde territory while neutralising warmth.
About Intercosmo
Intercosmo is the professional haircare and colour brand of Italy's Cosmesi family group, developed and produced in Bologna for use in salons across Europe. The Voilà 3C Intense range is the brand's flagship permanent colour line, designed around a low-ammonia formula and the "3C" promise of Coverage, Care and Colour intensity.
Key features
- Permanent high-lift colour: brightens natural light bases into super-blonde territory
- Cool ash undertone: the .10 ash reflects neutralise yellow and orange warmth in lifted hair
- Low-ammonia formula: reduces typical sting and odour while still lifting and depositing pigment
- Conditioning agents: the 3C formula is built to leave hair feeling soft and looking shiny
- 1:2 mixing ratio for super-blondes: enables greater lift than standard ratios
Who it's for
Best for natural light-blonde to medium-blonde bases (around levels 7–9) who want to lift their colour into a platinum or cool-ash blonde, or maintain a high-lift blonde that's been previously coloured. The ash reflect is especially useful for those whose hair tends to lift warm. Suitable for use at home only with experience or by a professional colourist — high-lift blondes need careful timing.
How to use
- Carry out a strand and skin allergy test 48 hours before colouring.
- Mix Voilà 3C Intense with the recommended Intercosmo developer at the high-lift ratio (typically 1:2 for super-blondes — check the box).
- Apply evenly to dry, unwashed hair, working in sections from roots through to ends.
- Leave to develop for 30–50 minutes depending on the desired lift and hair condition; check progress regularly.
- Emulsify with a little warm water, rinse thoroughly, and finish with a colour-safe shampoo and conditioner — purple shampoos help maintain the cool ash tone.
