Helpful product if you have somewhere to go and need immediate root touch-up. I am blonde with brown roots without grays. It does not cover completely, it just doesn't make the root-to-hair difference so intense. The negative is that it requires a lot of product to cover my part and hairline, resulting in it finishing very quickly (3-4 applications).

Unfortunately, the product does not live up to the expectations it creates. There was no difference in the color of my hair. It was as if I didn't even use it. It didn't cause any allergic reaction, but it is completely useless. I would not buy it again. Essentially, I wasted 10€.

A fine solution for the roots until I dye them. It sprays easily and covers satisfactorily. It lasts about 2-3 days, it's good to renew it. Of course, the color is not exactly in my shade, but expected... I use it regularly.
