How long does the Wine Red V48 colour last, and how does it fade out?

The Wine Red V48 is a temporary toning shampoo, which means it works by coating the hair surface with colour pigments instead of penetrating the hair structure like an ammonia-based dye. Because of this, the colour gradually fades over roughly 4–8 washes. The exact number depends on how often you wash your hair, your hair type, and the shampoo you use afterwards.

Fading is gradual, so you won't see a sudden change. On lighter hair, the red tone may appear brighter and more vibrant at first, then fade to a softer pinkish or coppery tint. On darker brown hair, it shows as a rich red reflection and gradually returns to your original shade. To make the colour last a bit longer, you can wash your hair less frequently, use lukewarm or cool water, and choose a gentle, colour-safe shampoo. But remember, this product is designed for temporary changes, so the fade is expected.
