This product works well, providing gray coverage as advertised, at a competitive price. To prevent nail discoloration, it's recommended to thoroughly wash your hands with an antibacterial soap or dishwashing liquid immediately following application.

I searched for the easiest way to get my hair back to its natural state, and Just for Men Control GX delivered. It’s quick, easy to use, and has a pleasant scent—sweet, but not overpowering. My hair had started turning gray in a few areas, and within days, it had returned to its natural black. The color holds well with no rub-off, which was a big plus. I wouldn’t recommend it for lighter hair tones, but if your hair’s black like mine, it blends in perfectly. Even my barber was surprised and asked what I’d been doing—my hair looks fuller and darker, just like it used to. It’s also gotten a little thicker, just as promised. Only caution: don’t leave it sitting on white countertops or bathtubs; it can stain if you’re not careful. Overall, I’m extremely pleased with this purchase, especially considering the price.

Works, but it does have a fairly strong scent to it.

Careful. This product works better than the Control GX. What I mean as being careful is that don’t let the product stay on your skin longer than 5 minutes. It will stain your skin. I was able to reduce my grays significantly in 3 days. Compared to others that I’ve tried, where I have to let it stay for about 10 minutes. Yes, it can stain your nails, obviously. It’s the same composition of hair. Recommend buffing your nails or wear gloves prior. Not sure about thickening the hair as I don’t have thin hair. I didn’t get any skin reactions nor itching.

I'm 43 and have some light greying, not even close to going full grey, but enough that it is noticeable if your talking to me. I used the regular just for men grey reduction shampoo for the first time about 4 months ago because the grey in my sideburns was getting more noticeable and it bugged me - not sure why my sideburns decided to go almost full on grey while the rest of my hair had only scattered grey - but Ebenezer scrooge side burns just wasn't working. The original formal worked just enough that I bought it a second time. Decided to try this one out after the last bottle of the original formal ran out and it is much better: my hair seems to absorb the dye better, it definitely works better on thinner portions of hair like sideburns and hair cut with a clipper, and it does actually help to make my hair look thicker. Not sure if this is good for someone who is mostly greying but definitely is a decent option for anyone like me who has just started to get greys. Just note that it does not fully get rid of all of your greys but makes them less noticeable and blends them in much better. I use this about 2 times a week, if you used it more you might see more extreme results. If you don't want to use hair dye then this is a good option and it is better than the regular grey reduction by Just for Men. Worth the extra $$.
