L’Oréal Professionnel Dia Light

L’Oréal Dia Light is a professional, ammonia-free, tone-on-tone colour designed to revitalise, refresh, and enhance the beauty of sensitised, coloured, or over-processed hair. Its acidic gel-cream formula provides exceptional shine, improved hair condition, and long-lasting colour vibrancy without lightening the natural base. Ideal for colour-refresh services, glossing, neutralisation, or soft tonal changes, Dia Light delivers uniform, luminous results while leaving the hair feeling smooth, healthy, and nourished.

Perfect for clients who want colour maintenance between permanent colour services, wish to neutralise unwanted tones, or desire a glossy, reflective finish.
