I’ve used this shade on my grey hair and it covers perfectly. The color is bright but natural, and my hair feels smoother after application. No frizz or dryness, which I appreciated.
Elizabeth Knox –
The result is vibrant and true to the shade. I noticed a gentle lift, which is perfect for my medium grey. My hair stayed looking fresh for over a month without fading.
Sally Ross –
Great coverage and the formula feels gentle on the hair. It’s not too heavy, and the shine is natural. A bit more coverage than expected on very light grey areas.

I’ve tried several permanent dyes, but this one stands out for its balance between brightness and natural look. The argan oil really helps with softness.

The color lasts longer than other shades I’ve used. My hair still looks fresh after two weeks. Slight lift is noticeable but not overwhelming.
