PRIMARY USES

1. Acidic Demi-Permanent Gloss Color for Tonings and Refreshing
  • What it does: Dia Light 7.11 is an ammonia-free, acidic demi-permanent gloss color specifically formulated to gloss, tone, and refresh color on previously colored or sensitized hair . The unique acid-gel cream technology with acidic pH smooths the cuticle for a vinyl-like finish, providing ultimate shine while adding tone without any lift . The shade 7.11 Deep Ash Blonde offers intense cool reflects for sophisticated, neutralized results.
  • How it helps your hair: For the person who wants to neutralize unwanted warm and brassy undertones in their medium blonde hair while adding a cool, sophisticated finish, this provides a gentle, low-commitment solution that leaves hair up to 30% more conditioned . For anyone seeking a fresh, clean ash blonde look without the harshness of permanent color, this means an ammonia-free formula that respects the hair’s integrity while delivering professional results.
2. Enriched with Acid-Gel Cream Technology for Deep Hydration
  • What it does: The formula features unique acid-gel cream technology with an acidic pH close to the natural pH of hair, ensuring a seamless blend of color while sealing the cuticle for a vinyl-like finish . The gentle formula provides intense care for the hair, neutralizing reflects after lightening and balancing the hair’s pH level . After application, hair is up to 30% more conditioned and 2x glossier compared to oxidative colors .
  • How it helps your hair: For the person whose hair feels dry or damaged from previous lightening or coloring services, this provides a gentle toning experience that improves hair condition. For anyone who wants their color service to nourish rather than compromise their hair, this means a formula that hydrates and strengthens while it colors.
3. 3-in-1 Professional Tool: Gloss, Tone & Refresh
  • What it does: Dia Light is specifically designed as a 3-in-1 professional tool for glossing (adding shine and manageability), toning (neutralizing unwanted undertones after lightening), and refreshing (reviving faded color on lengths and ends) . The versatile formula allows stylists to customize results based on client needs, from subtle shine enhancement to visible tonal changes.
  • How it helps your hair: For the person with unwanted brassiness in medium blonde hair, this provides a toning solution that neutralizes warmth while adding cool ash reflects. For anyone wanting to add shine and dimension to their color between salon visits, this means a versatile product that adapts to your specific needs.
4. Provides Zero Lift with Up to 2.5 Levels of Darkening
  • What it does: Dia Light provides zero lift (does not lighten natural hair color) but can darken hair up to 2.5 levels depending on the developer used . The formula does not increase length sensitivity or burden the hair, making it ideal for color-treated or sensitized hair that needs a refresh without additional damage.
  • How it helps your hair: For the person who wants to refresh or darken their existing color without further lightening, this provides a safe, gentle option. For anyone with fragile, color-treated hair, this means a formula that respects the hair’s condition while delivering beautiful results.
5. Mixable with 6, 9, or 15 Volume Developer for Customized Results
  • What it does: Dia Light mixes at a 1:1.5 ratio (1 tube color to 1.5 parts developer) with DIActivateur 6-vol (1.8%), 9-vol (2.7%), or 15-vol (4.5%) depending on desired opacity and service type . 6-vol provides softer color deposit ideal for blondes and sensitized hair; 9-vol delivers standard tone-on-tone results; and 15-vol offers stronger deposit for more opacity. Development time ranges from 5 to 20 minutes depending on desired intensity .
  • How it helps your hair: For the stylist, this provides the flexibility to customize the opacity and intensity based on client needs. For the client, it means a tailored service that can range from a subtle gloss to a more noticeable color refresh, with results lasting up to 6 weeks .
6. Not Designed for Grey Coverage
  • What it does: Dia Light is not recommended for white hair coverage; for white hair coverage of up to 70%, L’Oréal Professionnel recommends Dia Color . This shade is specifically formulated for toning, glossing, and refreshing previously colored or sensitized hair.
  • How it helps your hair: For the person with no or minimal grey coverage needs who simply wants to tone, refresh, or add gloss to their medium ash blonde hair, this provides the perfect solution. For those with emerging grey, Dia Color is recommended for full coverage results.

SECONDARY USES

1. Glossing Service: Apply to all-over hair with 6 or 9 volume developer for 5-10 minutes to add intense shine, improve manageability, and deposit subtle color reflection without altering the base shade . For the person who wants a “gloss” service between color appointments, this provides a quick, low-commitment shine boost.
2. Toning After Lightening Services: Apply to pre-lightened or balayaged hair to neutralize unwanted warm and brassy undertones using 6 or 9 volume developer, processing for 10-20 minutes . For the person who has just had highlights or balayage and wants a clean, cool finish, this provides the perfect toning solution.
3. Refreshing Faded Lengths and Ends: Apply specifically to mid-lengths and ends after a permanent color root touch-up to revive faded color and ensure a seamless match, using 9 or 15 volume developer, processing for 20 minutes for a more pronounced effect . For the person whose blonde ends have faded faster than their roots, this provides an even, refreshed result.
4. French Balayage Toning: Use to neutralize lightened strands after a balayage service without affecting the natural base, processing for up to 20 minutes . For the person with hand-painted highlights wanting a cool, sophisticated ash finish, this provides a professional toning solution.
5. Pre-Coloration Treatment: Suitable for pre-coloration techniques to even out porosity on damaged or sensitized hair before permanent color application. For the person whose color turns out darker on the ends than at the roots, this provides a preparatory step that creates a more uniform canvas.
6. Corrective Color Applications: Suitable for corrective color applications to neutralize unwanted undertones or refresh faded color on color-treated hair. For the person with uneven color results, this provides a corrective solution that creates a more uniform, balanced finish.
