Control GX by Just For Men is a gray reducing shampoo that claims to work gradually and leave you with subtle, natural-looking results in just two to four weeks.

In other words, unlike much of the competition, Control GX promises to never completely get rid of your gray, while still providing you with thoroughly clean hair that’s thicker, fuller, and revitalized, just like your regular shampoo.

Then, once you’ve reached a shade you like, Just For Men claims you’ll only need to use Control GX a few times per week for maintenance.

If you arrived here from the Control GX website, you might be buzzing with excitement. But did you know that the company notes it’s best for light brown to black hair?

What if you have a different color hair? Are there any other important considerations you should keep in mind before you pay for Control GX Shampoo? Stick with us, and we'll cover the most important aspects here.

How Much Does Control GX Shampoo Cost?

If purchased from Just for Men, a 5 oz bottle of Control GX Shampoo will cost you $8.49. The company also makes a 2-in-1 Shampoo & Conditioner for the same price if you’re looking for more manageability.

You can save $2 by joining the company’s JFM rewards program, while Control GX can also be found at third-party retailers like Amazon, Target, and Walmart for about the same price.

Now, let’s start with some ground rules about different types of hair dye.

The Basics of How Hair Dye Works

You’re busy, so we’re not going to waste your time with a bunch of scientific mumbo jumbo that doesn’t answer your fundamental questions about how Control GX works.

In a nutshell, though, Control GX belongs to a class of dyes known as demi-permanent. Every product in this class contains an alkaline agent other than ammonia (which only permanent dyes feature), such as ethanolamine or sodium carbonate.

Using these fundamental ingredients, demi-permanent dyes are known for their ability to effectively cover gray hair and provide more blended, natural results than others. This is because they don’t remove natural hair color, so not all of your hairs end up the exact same shade.

Demi-permanents are also less harsh than permanent dyes and wash out over 20-28 shampoos if you don’t like the results.

Specifically, what ingredients does Control GX’s demi-permanent dye contain?

Do Control GX’s Ingredients Amount to a Different Type of Hair Dye?

Control GX Shampoo contains:

Water/Aqua, Disodium Lauryl Sulfosuccinate, Decyl Glucoside, Cetearyl Alcohol, Glycol Stearate, Ethanolamine, Cocamidopropyl Hydroxysultaine, Guar Hydroxypropyltrimonium Chloride, Sodium Cocoyl Isethionate, N,N-Bis (2-Hydroxyethyl)-p-Phenylenediamine Sulfate, Acetic Acid, Aloe Barbadensis Leaf Juice, Chamomilla Recutita (Matricaria) Flower Extract, 1,2,4-Trihydroxybenzene, Cetearyl Glucoside, Erythorbic Acid, Sodium Sulfite, Phenoxyethanol, Caprylyl Glycol, Stearamide AMP, Panthenol, Manganese Sulfate, p-Aminophenol, Sorbic Acid, Etidronic Acid, Fragrance/Parfum, Limonene Linalool.

Remember the ethanolamine we just talked about? Its sixth place on GX’s ingredients list firmly plants it in the demi-permanent dye category, although N,N-Bis (2-Hydroxyethyl)-p-Phenylenediamine Sulfate appears to be the product’s actual dying agent.

Outside of this—like most personal care and grooming products—all of Control GX’s other ingredients work to improve the texture, consistency, skin feel, and moisturization abilities of the shampoo.

How does this formulation compare to other demi-permanent dyes?

Are There Other Shampoo Dyes Like Control GX by Just For Men?

If you’re looking for demi-permanent dyes to help cover your gray, whether for your hair or your beard, you have many popular options. These include national brands like Redken, Clairol, L’Oreal, Paul Mitchell, and of course, Just For Men, most of which range in price between $6 to $15.

Comparatively, the biggest difference is that traditional options come in bottles that must be applied very carefully to your hair. You’ll typically need to wear plastic gloves and protect all your surroundings from any potential splatter.

Then, you’ll need to leave the dye in place for 10 minutes or so, and then hop in the shower to rinse it out.

On the other hand, since Control GX is shampoo, we're told you simply apply it while you're already in the shower, leave it in for a minute, and then continue your day as normal.

Does this different application process necessarily mean you won’t need to use any gloves with Control GX, though?

What’s Everyone Saying In Their Control GX Reviews?

Just For Men released Control GX Shampoo a couple of years ago, so it's had plenty of time on the market to garner some meaningful customer feedback.

Between Amazon and alone, we found 200+ customer reviews for Control GX, who had given the shampoo an average rating of about four stars. What was everyone saying?

In general, most compliments related to effective gray hair reduction that looked natural and ease of use. On the other hand, common complaints referenced allergic reaction (even one customer who performed the 48-hour test), stained fingernails, messy application, and mixed/unnatural results.

As far as the company themselves, Just For Men Products are manufactured by Combe Incorporated, who seemed to have a similarly positive online customer reputation.

What’s the Bottom Line About Control GX Shampoo by Just For Men?

Based on this extensive customer feedback, it seems like there are five main takeaways if you’re considering a Control GX Shampoo purchase:

  • The company requires that you perform a 48-hour skin allergy test prior to normal use. This could potentially help you avoid chemical burns and/or allergic reactions, but it means you shouldn’t use it for at least a couple days after purchase.
  • While it might be easier to apply, customers report that Control GX is still messy. Like other dyes, it also has a tendency to stain, so be sure to clean up the shower area when you’re done and use an old towel to dry off.
  • While not required, you might want to wear plastic gloves to avoid stained fingernails.
  • Although Just For Men claims Control GX can work on any hair color, you’re much more likely to achieve satisfactory results if you have brown to black hair.
  • Finally, multiple customers reported that if your hair is very short (1/4” or less), you might not get the results you’re hoping for.

In the end, there don’t seem to be any other products currently on the market. So, if you’re looking for a shampoo-in demi-permanent dye, it’s the only game in town.

Will it work better than the competition, or provide more natural-looking results than Just For Men’s other products? Because we’re all different (including preferences), you’ll just have to give it a whirl and find out.

But to perhaps save yourself a couple of bucks in S&H (not to mention time if you're dissatisfied and process a return), you might want to pick up a bottle of Control GX Shampoo from a local retailer, versus placing an order online.
