A: Dia Light is an acidic crème demi-permanent gloss color from L'Oréal Professionnel, now improved with Hyaluronic Acid. It's designed to gloss, tone, and take-through, delivering instantly decreased dryness, 1.9x more hydration, and 82% glossier color, while respecting cortex integrity and strengthening hair after lightening.
A: The new Dia Light formula, powered by Hyaluronic Acid, deeply hydrates and enriches hair, resulting in +82% glossier color that lasts up to 6 weeks. It helps respect cortex integrity with less breakage, balances hair after lightening, and seals the cuticle. Its new milky crème texture is preferred by pros and offers a more treatment-like feel.
A: Dia Light uses a 1 to 1.5 mixing ratio. This means you mix one tube (2 oz.) of Dia Light with 3 oz. of DIActivateur developer (available in 6-vol., 9-vol., or 15-vol.), depending on the desired intensity of the result.
A: The development time for Dia Light ranges from 2 to 20 minutes. This timing can vary based on the specific service (e.g., toning, lowlights, color match refresh) and the desired level of fade or intensity.
A: Dia Light's acidic pH technology is crucial for gently depositing dyes and perfectly balancing the hair. It works by sealing the hair cuticle, which enhances reflect and deposits tone without lifting the natural pigment. This acidic environment also helps to reduce dryness and maintain optimal moisture levels in the hair.
A: No, Dia Light is a zero-ammonia demi-permanent gloss color. Its unique acidic pH helps preserve the integrity of the hair.
