Superb product does exactly what it says. Highly recommended. 5*

After 2 weeks my friends commented without prompting that my hair looked darker again and asked what I was doing.

After a few days, I was a bit skeptical about how the colour started changing from gray to some indefinite colour, but to my surprise, after a few days, my natural color actually came back! Thank you! 🙂


Very happy to date and can’t believe the results came in such a short space of time.

Still not convinced?
