The color turned out exactly as expected—rich and warm without being too bright. My hair feels soft after the application and the color stays vibrant even after two weeks of regular washing.
Ryan Mathis –
I applied it to medium brown hair and it gave a beautiful copper tone. The process was smooth and the color didn’t feel heavy. Slight fade after a week, but still looks great.
Sam Piper –
Great for adding warmth to my dark hair. No harsh chemicals, and my hair didn’t feel dry or damaged after the treatment. I’m happy with the natural finish.
Peter Walker –
The color is nice, but it required a longer processing time than I expected. I had to extend it to 40 minutes, and it felt a bit more intense than I wanted.

Perfect for a subtle copper glow. The shade is balanced and looks natural with my skin tone. I plan to use it again for a touch-up.
