I used Just for Men for 20 years and then my face started getting very itchy but I still used it. A couple of months later, I was washing it off in the shower and my face got numb and felt like rubber. I rushed to the emergeny room thinking I had an anaphylactic shock and my throat was going to close up. They gave me predisnisone but by the time they saw me, my numbess subsided. I did not want to use the dye ever again as it may have worse consequences. I switched to mascara which was effective inside but outside, my beard looked greyish and the summer heat melted it. I was sceptical about trying Volt so ordered the sample pack. After I applied it, I was preparing for an allergic reaction but happy to say it never came. And it did hold up through the next day and a shower without coming off. Really great product! I now ordered the refill pack. My wife is going to start using it for her eyebrows. I turn 70 this August so I wanted to not look like an old man since I don't have many wrinkles!
