Irene Gibson –
The color is very natural and doesn’t look heavy. I used it on my grey hair and it covered it completely without looking unnatural. The application was easy and the results lasted well. I didn’t have any irritation, which was a relief after previous colorings.
Wendy Parsons –
Great coverage and shine. The color blends well with my natural hair. I followed the mixing ratio exactly and it worked smoothly. The product feels more gentle than others I’ve tried, though I still had a slight sensitivity after application.
John Piper –
I’ve used several hair dyes before, but this one feels the most balanced. It gives a soft, natural look with depth. The ME+ feature is reassuring, especially since I have a history of allergic reactions to hair products.
Lucas Dickens –
The color is good, but it requires precise mixing. I had to follow the instructions carefully. It covers grey well, but the lift level is not as strong as I expected for my dark hair.
Penelope Hunter –
The result was stunning. My hair looks healthy and vibrant. I didn’t experience any allergic reaction, and the shine is natural. I’m happy with the product and will use it again.
