FAQs
What can L’Oréal Dia Light be used for?
Dia Light is a tone-on-tone, acidic gloss colour that refreshes and tones previously coloured or sensitised hair. Use it after lightening services to refine tone, add shine and improve your client’s hair condition.
Is Dia Light a toner range or a hair colour range?
It sits between the two, working as a tone-on-tone colour system. This means it deposits pigment without lifting the natural base, and can be used as toner for pre-lightened hair as well as refreshing existing colour and enhancing reflects.
What makes Dia Light different from other toners?
Unlike many other toners, Dia Light’s acidic gel-cream technology is ammonia-free and helps seal the cuticle for a high-shine, vinyl-like finish and improved condition, without lifting colour or lightening the hair.
What’s the difference between Dia Light and Dia Color?
Dia Light uses an acid gel-cream formula designed for glossing and toning hair with no lift. Dia Color (formerly Dia Richesse) is a demi-permanent dye that uses an alkaline formula to offer more depth, up to 70% grey coverage and suitability for more general colour services.
What are some of the most popular Dia Light shades?
Some of our bestselling Dia Light shades include: Dia Light 9.1 (Ash Milkshake), 6.34 (Dark Gold Copper Blonde), 7 (Blonde) and 6 (Dark Blonde).
How do I choose between Dia Light, Booster and Acidic Gloss Clear/Colour?
The Dia Light range can be customised to your client’s needs. Understanding the key differences will help you choose between the products:
- Dia Light: This is the core shades range in 50ml tubes, used for toning, glossing and refreshing colour. Shades are perfectly paired with L’Oréal Majirel and INOA colours.
- Dia Light Booster: These can be mixed with Dia Light core shades to boost neutralisation, intensify reflects and create personalised results.
- Hyaluronic Acidic Gloss Colour: This is a next-generation Dia Light gloss formula enriched with hyaluronic acid to hydrate, improve feel and deliver high-shine results.
- Acidic Gloss Clear: Fluidifies the texture for easier take through, and used to dilute tone, soften intensity or create a pure gloss service.
