Introducing L'Oréal Professionnel Dia Light 50ml

L'Oréal Professionnel Dia Light is an advanced, ammonia-free, semi-permanent, tone-on-tone colour designed to create a gentle toning process. With its signature acid-gel cream technology, Dia Light delivers a soft and effective approach for beautiful hair tones. The formula results in remarkable shine, making hair look glossier and healthier after every application. Users enjoy enhanced conditioning—up to +30% more—leaving hair silky, vibrant, and fresh.

The neutralising gloss technology behind this product works on all hair bases, allowing endless toning choices. Whether you’re searching for cool ash effects or warm beige hues, the formula ensures there’s an option for everyone. This careful formulation helps the colour look natural and luminous while ensuring the strands are protected from excess damage. Both professional colourists and individuals benefit from its reliable, gentle shine boost and dependable care for hair.

Shine and Conditioning Technology

Shine is a top benefit with this innovative product. The unique acid-gel cream solution works to smooth the cuticle of each hair strand. As a result, hair looks healthier and more reflective, producing a glossy effect that clients love. Many notice immediately how their hair feels hydrated and more luxurious after use.

Special conditioning agents blend into the formula to provide deep moisture. This gives up to +30% more conditioned hair than untreated strands. The added moisture helps control frizz, tames dryness, and leaves hair with a soft, silky look that endures between visits.

Versatile Toning for All Hair Types

Professionals enjoy the freedom to create personalised colour results for every client. The broad selection of toning shades means options for both subtle and creative looks. This product can revive faded colour, neutralise unwanted tones, or add striking gloss to natural hair.

From natural beige to modern ash variations, the formula is suited to anyone hoping to elevate their shade. Those wanting to enhance their current colour or experiment with a gentle change will appreciate the delicate result and easy, semi-permanent application.

Tone-Only Colouring

• Deposits tone only. Zero coverage of white hair. Zero lift. Ideal for previously sensitised or coloured hair.

This product will not lighten or lift the hair colour. It focuses on gentle toning, simply depositing colour for subtle results. Best for individuals with coloured or sensitised hair seeking a mild touch. For full coverage of white or grey strands, consider another L'Oréal product from the professional range.

If your goal is to refine tone, revive vibrancy, or add noticeable shine without a big change, this product is an ideal solution. Top professionals use it as a final step or glossing service for that salon-fresh finish with every appointment.

DURABILITY

The effect of this semi-permanent hair colour lasts up to 4 weeks, allowing for extended enjoyment. The longevity varies depending on hair type, upkeep, and how often you wash your hair.

Gentle on hair, the formula protects against premature fading and damage. Loyal clients who commit to regular treatments see consistently luminous, fresh results throughout each cycle.

DEVELOPMENT TIME

The professional recommends a development time of up to 20 minutes for best results. Total salon service may differ based on individual needs or other treatments. This timing makes it convenient for clients who value efficient, high-quality colour.
