The color is very natural and covers grey well without looking harsh. I’ve used it twice now and my hair has a healthy shine. The application is easy and the results are consistent.

Great coverage and the color stays vibrant. I noticed less irritation compared to previous brands. Still recommend doing a patch test before first use.
