The color is very natural and covers grey well without looking harsh. The application was smooth and the shine is excellent. I did the allergy test as advised and had no issues. Great for daily use.
Matt Ross –
I’ve used several hair dyes before, and this one feels the most balanced. The lift is subtle but effective. The color stays vibrant for weeks. Just make sure to do the allergy test before applying.
Sebastian Skinner –
The shine and depth are outstanding. My hair looks healthier after each use. The 1:1 mix is easy to follow and the results are consistent. I recommend it for those seeking natural-looking color.
Leonard Langdon –
It covers grey well, but the lift is not as strong as I expected. I think it’s better suited for light to medium grey. The color is balanced, but not as vibrant as some other brands.
Sebastian Lewis –
I’ve used this product twice now and it’s maintained the color well. The hair feels softer and shinier. The allergy test was required, and I’m glad I followed it. Very satisfied with the results.
