Discover the Caviar Infinite Colour Hold Serum by Alterna, a multi-purpose formula that protects colour vibrancy and visibly enhances shine. The nutrient-rich serum utilises caviar extract and a Dual Capture Complex to shield the lengths from dulling environmental aggressors, helping to minimise the risk of fading. Delivering heat protection up to 232°C, the versatile formula can be used alone as a leave-in treatment, or combined with any Alterna conditioner to create a nourishing mask. Hair feels hydrated with a smooth, luminous appearance.
