## Long description

L’Oreal Paris Dia Light N 7.40 professional demi-permanent dye 50 ml is a salon-grade color product designed for gentle tone enhancement and temporary colour change. The formula deposits pigment without aggressive oxidation, providing natural-looking warm tones, improved shine and subtle correction of existing shades. Packaged in a 50 ml tube, this demi-permanent dye is intended for use where low-damage, short-term colour results are desired.
Advantages
This demi-permanent dye delivers even, buildable colour with minimal damage to the hair structure due to its non-oxidative, low-ammonia formulation. It enhances shine and softness while blending or neutralising unwanted tones, and it can refresh faded colour without lightening natural hair. The 50 ml size suits targeted applications such as root blending, colour glazing and toning between permanent services.
Suitable for
Refreshing faded salon colour
Toning and neutralising brassiness
Subtle warmth enhancement on previously coloured hair
Colour glazing and shine finishing
Short-term, low-damage colour changes
Key specifications
Formulation: demi-permanent, low-oxidation
Tone: warm chestnut (7.40)
Volume: 50 ml tube suitable for targeted applications
Colour result: natural-looking deposit without lightening

How to use
Apply according to professional instructions or the included leaflet. Mix the product with the recommended developer or activator specifically intended for demi-permanent use, following the specified mixing ratio. Work on clean, towel-dried hair, applying evenly to the areas requiring tone adjustment or refresh. Leave on for the manufacturer-recommended processing time, then rinse thoroughly until water runs clear and condition as usual. Perform a strand test and sensitivity test prior to full application.
Usage recommendations
Use for toning and refreshing existing colour rather than lifting natural hair pigment; for best results, consult a professional colourist when adjusting tones beyond subtle enhancement.
