Guys, now no one can even comment here. I got this dye, I applied it the first time according to the instructions (now it says 10 minutes), I didn't get full coverage, but the result was good. I used about half a bottle, you could tell it couldn't take more, because my head was dripping. It lasted about a month, everything was fine up to that point.

After the first month I used the other half of the bottle, guys it seems to me that after the second wash it all came off. Does it lose its potency?

Very good product with a good application.
It gives an almost natural shade to the hair.
I highly recommend it.
As for those who write about red and... green shades, that's not true. (If they don't know how to read and follow the instructions for use, they should go to a hairdresser... )

Simply amazing! I got it for my husband and it was the best choice. I was impressed that it didn't stain the skin at all. Highly recommended

You need about one box per month to keep the color right... Its quality is very good!! Maybe for the back of the neck, you might need help from someone or a mirror behind you!!!

After the 2nd application, absolutely satisfied. Damn, I looked ten (10) years younger. It lasts comfortably for 4 weeks (washing twice a week)

I read the comments carefully before buying it. I left the dye on for 3 minutes because I was afraid it would come out too dark as other users mentioned. The coverage was minimal. The many white hairs at the temples were hardly covered at all. I reapplied and left it for another 4 minutes, the coverage was better but still not great.

**UPDATED** I dyed them again after 2 months using the leftover dye and this time I used much more and left it on for 5 minutes. The difference was huge. The color was very intense and all the white hairs were covered. I had used too little dye the first time. So pay attention to the ratio. The naturalness of the color is excellent. It is very good but I give it 4 stars because the dye is toxic, you feel the burning sensation in various spots on the skin. The smell is also strong.

Just fine. If you want, you can leave it for only 3 minutes for a more natural result, meaning to keep some gray as well.

I think it is the king of men's hair dyes. The result is perfect. It just requires a little attention to the "timing" of how long the dye will stay on before washing, meaning that the longer it stays, the darker the color becomes. It lasts up to a month.

Attention with the times only! And the 5 minutes may be too much. 4 is fine. Also, if you have a precision scale, divide the dye into a bowl of 20 by 20 ml so that you have enough for another time.

It is for single use. So, for a man who simply wants to lightly color his cheeks, it does not work.

I describe my friend's experience with light brown hair and lots of white. He tried the light brown and it turned out yellow-green. When he told me on the phone, I thought he was exaggerating, but then I saw it myself. So be careful!!
