L'Oréal Professionnel Dia Light — a soft gloss-color for spring

No ammonia, no dramatic color change — Dia Light is a gloss treatment that deepens your natural color, exactly the subtle refresh spring calls for.

L'Oréal Professionnel
Dia Light — bottle

Dia Light is L'Oréal Professionnel's first acidic demi-permanent colour, enriched with hyaluronic acid. It hydrates during the colouring itself and tackles dryness, one of the first visible signs of damage. In the salon the colour cream is mixed with the Dia Activateur into a creamy, evenly applied colour that doesn't weigh the hair down. Three treatments are possible with it: Hyaluronic Glossing for shine and suppleness, Hyaluronic Toning to neutralise unwanted undertones after lightening or a balayage, and Hyaluronic Refreshing to revive faded lengths and ends. According to the brand it gives up to 6 weeks of glossy colour, the formula contains no ammonia and it is vegan. Ideal after winter, when hair has gone dull but a full colour treatment isn't needed yet.
