Colour Dilution

L'Oréal Professionnel Dia Light Clear is an acidic, ammonia-free clear gloss specifically formulated to add ultimate shine, condition, and a vinyl-like finish to color-treated or sensitized hair without any colour deposit . This versatile 3-in-1 professional tool can be used alone for a pure glossing service—providing up to 30% more conditioned hair—or mixed with any pigmented Dia Light shade to dilute, pastelise, and personalise colour for subtle, luminous reflects .

The innovative acid-gel cream technology features an acidic pH close to the natural pH of hair, ensuring zero lift (no lightening) while sealing the cuticle for incredible shine . The clear formulation also fluidifies the texture of any Dia Light mixture, making application on lengths and ends faster, smoother, and more even .

Mix at a 1:1.5 ratio (1 tube of Clear to 1.5 parts developer) with DIActivateur 6-vol (1.8%) for subtle gloss or 9-vol (2.7%) for standard results . Development time ranges from 5 to 20 minutes depending on desired intensity .

This product is intended for professional use only. To use as a pure gloss, mix 1 tube (50-60ml) of Dia Light Clear with 75-90ml of DIActivateur Developer, apply to dry, unwashed hair using sectioning techniques, process for 5-20 minutes, then emulsify, rinse thoroughly, and follow with a post-color shampoo . Always perform a patch test 48 hours before any coloring service.
