Professional demi-permanent gloss for coloured hair

L'Oréal Dia Light 7.40 Firelight is an ammonia-free gel-cream colour designed for tone-on-tone refreshment of previously coloured hair. Its acidic formula delivers luminous colour and vinyl shine while conditioning the hair. The 50 ml tube is intended for salon use by trained professionals only.

Replaces permanent colour for interim vibrancy

Instead of a full permanent service, this demi-permanent gloss revives faded tones between appointments without lifting the natural base. The jump is worth it when the client wants enhanced shine and condition without the commitment or damage risk of oxidative permanent colour. Mixed 1 to 1.5 with Diactivateur 6, 9 or 15 volume, it develops in 20 minutes.

Fits into a colour-refresh workflow

The product requires Diactivateur developer in 6, 9 or 15 volume and a non-metallic bowl and brush for mixing. It frees up the stylist from ammonia fumes and long processing times while delivering a conditioned, high-gloss result on normal hair. Made in Spain for professional salon environments.

Questions about this item

What developer volume and mixing ratio does the 50 ml tube of 7.40 Firelight require?

Mix one part colour with one and a half parts Diactivateur at 6, 9 or 15 volume for the correct consistency.

Which step in the 20 minute development process is most often missed?

Timing starts only after the full mixture is applied evenly; rinsing early gives uneven tone.

How frequently will a top-up with this demi-permanent gloss be needed?

Expect to refresh every four to six weeks as the tone-on-tone colour gradually fades.
