L'Oréal Professionnel Dia Light Booster 50ml

L'Oréal Professionnel Dia Light Booster (50ml) is an ammonia-free colour enhancer designed to expand and personalise the Dia Light palette with intensified reflects and refined tonality. These acid-gel cream boosters blend seamlessly with any Dia Light shade, allowing for custom colour creation tailored to each client's unique hair goals.

Available in six versatile shades, the boosters are ideal for boosting vibrancy, enhancing cool neutralisation, or creating fashion-forward effects like glossy bronzed lengths. The Violet Booster, in particular, pairs beautifully with Metal Detox treatments for luminous, trend-led results.
