Questions about this item

How often will the 6.66 Dark Blonde Intense Red shade need a refresh on normal hair?

The demi-permanent formula is designed for colour refreshes between permanent services; expect to reapply every few weeks as the tone-on-tone colour gradually fades with washing.

What limits how long the colour stays vibrant under daily washing?

Because it is an ammonia-free, semi-permanent gel-cream, the pigment sits on the cuticle rather than penetrating deeply, so frequent shampooing is the first factor that reduces vibrancy.

Does the mixture generate noticeable heat or fumes during the 20-minute development time?

The acidic, ammonia-free gel-cream mixed 1 to 1.5 with Diactivateur 6, 9 or 15 volume develops at room temperature without strong odour or noticeable heat.
