Control GX + THK Thickening Shampoo with Grey Reduction, Shampoo for Thinning Hair with Alpha Keratin, Thickens Hair Up to 20%, Works with Every Hair Texture, 4 oz

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.

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 $$.

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

If you were a past Control GX user and noticed that they changed the product in a bad way, try this one. It works like the old Control GX, except maybe a little better. Maybe it was a ploy to get people to pay more for this upgrade? Unlike old Control GX, there is no staining. Also feels more gentle on your hair. I hope they don't screw this one up.

Product seems to work, but they really should have it in colors. I have dark brown hair. I really feel like if I use this too much my hair turns black.

Great product

I love this Product!!! IT REALLY WORKS!!!! People always have problems with staining of fingers or nails... IT'S SIMPLE, JUST SPRAY SOME CLOROX CLEANUP ON YOUR FINGERS AND OR NAILS, LEAVE FOR A FEW SECONDS AND YOUR SITUATION IS GONE!!!

I have thinning, grey hair. I had looked for a shampoo that may help and found many reviews about this product being the best option. I started with the allergy test and found that this was a very liquid shampoo, not gel like. Others have stated this, and I can confirm that this came pouring out like water. 2 photos are attached to show the effect of the allergy test. While I was not allergic to the shampoo, the liquid nature of the shampoo spread all over my inside elbow and forearm. In my experience this is a hair dye and not a “shampoo.” In addition to my forearm, my opposite wrist brushed against my forearm during the test, and that is the other photo. It is now a week later and my arm is still stained. Due to this, I did not use the product beyond the allergy test. Not for me.
