Edward Chapman –
The color is very natural and covers grey well without looking harsh. I used it on my 50s hair and it gave a soft, balanced tone. The application was easy and the shine is noticeable after a few days.
Amanda Walsh –
Great coverage and the color stays true even after washing. I noticed less damage compared to previous brands I’ve used. Still, I recommend doing the allergy test before first use.
Sam Allan –
I’ve used several professional hair dyes before, but this one feels the most balanced. The lift is subtle but effective, and the hair feels healthier after coloring.
Max Hart –
The color is good, but I had to apply it twice to cover all grey. The instructions were clear, but the developer didn’t mix as smoothly as expected.
Diane Harris –
The natural depth and shine are impressive. I didn’t notice any dryness or frizz. My stylist recommended the allergy test, and I followed it — it was a good precaution.
