I’ve used this product for two months now and the color stays true. No darkening at the roots, and it’s easy to apply with the comb-in tool. My hair feels healthy and the process is much simpler than other hair dyes I’ve tried.
Jan Oliver –
The auto-stop feature works well. I applied it to my gray hairs and it stopped exactly where I wanted. No over-processing, and the color is even from roots to tips. I appreciate the ammonia-free formula.

This is the first hair color that didn’t make my hair feel dry or brittle. The real black looks natural and lasts longer than expected. I’m happy with the results and the ease of use.
