Product Information

Full details

L'Oreal Paris Dia Colour in 6.60 Red is a professional-grade demi-permanent gloss designed for adults who want to enhance their natural hair with vibrant tones and a mirror-like shine. It is an excellent choice for individuals looking to try a new shade for the first time or revive dull, tired hair with rich, even color. While it provides exceptional color payoff and gloss, it is important to note that as a demi-permanent formula, it is intended to fade gradually over time rather than providing permanent coverage.

FAQs

Does this cover gray hair?

Dia Colour is a demi-permanent gloss and is designed to blend gray hair rather than provide full, opaque coverage.

How long does the color last?

The duration depends on hair porosity and your washing routine, but it typically lasts between 4 to 6 weeks.

Is this product ammonia-free?

Yes, the L'Oreal Paris Dia Colour range is formulated without ammonia to provide a gentler coloring experience.

Can I use this on previously bleached hair?

Yes, it is excellent for toning bleached hair, but always perform a strand test first as porous hair may absorb color more rapidly.

Is a developer included in the package?

No, this 60ml tube is a professional coloring agent and requires a separate developer purchase for activation.

Troubleshooting

Color appears uneven on porous hair

Use a light protein filler or a leave-in treatment on extremely damaged ends prior to application to ensure even absorption.

The shade is darker than expected

Reduce the development time during the next application or choose a lighter shade in the Dia Colour range.

Setup, Compatibility & Care

To use this product, you will need to mix the 60ml tube with the appropriate L'Oreal developer (activator). Always perform a patch test 48 hours prior to full application to ensure no allergic reaction occurs. When applying, use gloves to protect your hands and protect clothing with a cape or towel. After processing, rinse the hair thoroughly until the water runs clear and use a color-safe shampoo and conditioner to lock in the gloss. Avoid excessive heat styling immediately after coloring to maintain the integrity of the pigment.
