Good product. On wet hair, it may not cover everywhere and can leave patchy spots. For better, more intense results, it’s best to use it on dry hair. The result in the photo is from faded ginger hair—it turned out like this! I would buy it again!

It is excellent. The first time, because I was afraid, I left it on for 5 minutes. My hair is naturally light brown with some gray, not too many, and reddish highlights. It gave life and color to the highlights and a little to the natural color, and almost nothing to the gray. The second time I used more product and left it on for over 10 minutes. My natural color became soft and shiny, the highlights became more intense, and although it did not cover the gray, it gave it a subtle color and blended it with the natural hair so that it is almost not visible at all. I will definitely buy it again.

The mask is a rather dull reddish-brown copper.
It lasts 2-3 washes after application, but it does not cover gray hair at all, unlike other color masks such as Imel's.
For a more intense copper, you can mix it with Imel's copper; that's what I did when I saw that it doesn't have much intensity.
For refreshing the color between dye jobs, it's okay, especially if you don't have gray or dark roots, but in terms of color intensity and gray coverage it falls quite short.

I use it on my hair, which goes through bleaching and red dye twice a year. In between, when I see that the color has faded, this product makes it vibrant again, just the way I want it. I also consider it very good value for money, and the bottle lasts me a long time even though I use a large amount. Ideally, I shampoo and then dry my hair fairly well with a towel, apply the product and let it work for half an hour, and rinse with cold water.

Before I used the product, I had dyed my hair from blonde to copper, but the blonde came out with the washes. I got the product and applied it to damp hair and left it on for 30 minutes!! Perfect result!!

it does not offer coverage for roots or white hairs, but it keeps already colored hair vibrant until the next dyeing. It is easy to apply, rinses out with water, and leaves the hair light and soft. I recommend it even for oily hair because it does not weigh it down at all. The result lasts for 2-3 washes.

Very nice, I got it for my mom and sister, and we have 3 different blonde techniques. It just fades very quickly, in 3 washes, but it does what it promises

Indifferent. One of the worst color masks. I used it twice, no change, even a small one, in the color.

'Regarding the refreshing of the copper, it does a very good job. It's best to apply it with a brush for a more natural result. If you want a more intense effect, leave it on the hair longer, 15-20 minutes. As a nourishing mask, it is amazing. It leaves the hair soft as a baby's and gives it incredible shine.'

On a base of 5 to 6 (dark, that is) that faded to an orange-red, it gave a very nice cherry cola red color! So it works on darks too (I was a bit hesitant) and it moisturizes a lot as well!

I have dyed ginger hair (without bleaching and with relatively light roots). It definitely does not cover the roots and does not dye the hair. It gives quite a bit of shine, somewhat refreshes the vibrancy of the color (nothing crazy) and makes it VERY soft, and I have the impression that it helps quite a bit with frizz control. I use it once or twice a week as a treatment all over my hair for 2 hours and I am quite satisfied.

It stains quite a bit. Make sure to work with gloves so your palms don't turn orange. It does come out after a few washes, but... It adds intensity to the color and helps it not to wash out too quickly (it doesn't stop it, just delays it).. the hair is quite soft afterwards, for a mask-dye! I will buy it again.

Very nice product, does not cover white hairs, ideal if you want to maintain the length of your hair and only dye the roots.

On already dyed copper hair for color renewal and maintenance until the next dye. I applied it on wet hair after showering for 10 minutes, then rinsed it out with water only!

It is better to use it on dry hair for 15-20 minutes.
My hair was blonde beige and it came out like that.
Attention, it does not cover roots or white hair.
