Powered by Plex Technology ✨

Unlike ordinary permanent hair dyes, Smart Beauty Amethyst Purple includes Plex technology designed to support the hair while colouring.

Plex works throughout the colouring process to:

• Protect the hair structure during colour development

• Rebuild weakened bonds that can be stressed during colouring

• Restore softness, smoothness and shine

This means you can achieve bold purple colour while helping hair feel healthier, smoother and more resilient after colouring.

Who Is It Best For?

Amethyst Purple works beautifully if you want:

• Deep purple tones on pre-lightened blonde hair

• A rich violet glow over lighter brown hair

• Creative colour panels or highlights

For darker hair, pre-lightening may be needed for maximum vibrancy.
