What is French Glossing?

French Glossing is a new service from L’Oréal Professionnel Paris, offering professional gradient colour with a personalised glossy finish. The bespoke technique is only achievable in-salon, encouraging clients to your business and is perfect for upselling to your loyal clients in the chair for an upgraded service.


1 Permanent hair colour is placed at the root for perfect root coverage, using Majirel or iNOA.

2 Dia Light is used throughout the lengths to revive colour for a personalised glossy finish.

How do I achieve the French Glossing technique?

Dia Light is the key to create the weightless gloss and shine that many women want. The unique acidic pH gel-cream technology revives colour seamlessly, leaving hair up to 2X shinier* and 30% more conditioned.**

The heart of French Glossing is all about you. As the professional, French Glossing elevates the profession and those who can offer this bespoke technique will draw back clients to the salon and secure rebookings.

Discover endless bespoke results

The same winning Dia Light formula now includes five new shades, ranging from dark to light in sustainable packaging. Dia Light is colour coded and perfectly complements Majirel for your French Glossing Service. Meanwhile, the new Dia Light Clear can dilute colour for subtle transformations and can be used to fluidify the texture of any Dia Light mix for easier take through, with a fast and easy application***. Dia Light Clear is also available in an economic 250ml format, making your services more profitable.

Sustainable at heart

The pandemic has increased focus on the natural environment, with sustainability at the forefront of consumer’s minds. Dia Light’s recyclable tube is made of 95% recycled aluminium, while the caps**** and cardboard are fully recyclable and made of recycled material. L’Oréal Professionnel Paris is one step closer to playing its part in creating a green footprint.
