Just for Men 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.

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.

It does in fact work as advertised. The color seems to blend in better than the original product. I bought my second one recently but not crazy about the price. First bottle was $17, the second was $19 and now it's just under $18. Anything over $19 is not worth the extra money. It's good, but not that much better than the original.

Excellent works as expected. Great results!

My hair is white and thin. I am 83 years old and have used this product twice. It worked immediately for me. My hair is noticeably fuller and with somewhat less grey. Nice clean smell and I’m very pleased with the result.

This product darkens the hair as advertised; however, they add perfume to it which won't go away even after continued washing. Not clear who's brilliant idea it was to add perfume to a men's hair product but it definitely deters me from using it as much as I'd like.

I have light to med. Brown hair, gray was coming in heavy for a while mostly on my sides. I bought this, used it with no result the first few times. Ok, I think that's normal as it works slow. The next time, I got out of the shower, my hair was almost black all over. In the light, it had a kind of weird dark color. kind like dark dark navy blue. I used other shampoos to try to get it out, nothing worked. Until, I used a product called " color oops" I used that and, got out of the shower and, all my hair was back to my light to med. Brown. Thank god... This stuff is just terrible... If your in a similar situation, color oops is gold...

Just the right amount to use for gradual turn of hair while leaving a little bit of grey.
