Jonathan Hudson –
I’ve used Koleston Perfect 99/0 on my dark brown hair and it gave a very even, rich tone. The color stayed vibrant for over two weeks without fading. My hair felt softer after application, which I didn’t expect from a coloring product.
Stephanie Pullman –
The formula applied smoothly and didn’t feel harsh on my hair. I noticed less frizz and the color matched the sample exactly. A bit more coverage than I expected for a 99/0 shade.
Owen Davidson –
I’m a frequent colorist and this product stands out for its gentle formula. It doesn’t dry out the hair like traditional dyes. The result is a natural-looking, long-lasting color.
