What Is Control GX Shampoo?

By Derek Lakin
Published on: Feb 15, 2017

Control GX Shampoo by Just For Men claims to use breakthrough technology that can gradually reduce gray hair with each shampoo for subtle, natural-looking results.

The manufacturer tells us that you'll use Control GX just like any other daily shampoo. After a few washes, you'll notice a subtle reduction in the number of gray hairs. From there, you have complete control over how gradually your gray disappears at the start by using every day, or every other day.

When you’ve achieved the look you want—often within two to four weeks—you’ll continue using Control GX three to four times per week for maintenance. Results can last up to eight weeks.

In addition to gradually reducing your gray, Control GX Shampoo also promises to gently and thoroughly clean and revitalize hair, while increasing volume for a thicker, fuller look.

Just For Men’s lineup has been a staple among hair and beard coloring products for decades, but does this necessarily mean that their Control GX Shampoo is worth the money? Even then, is it really “shampoo with a brain”?

Here, we’ll discuss all the essential facts so you can make a more empowered purchase.

What Causes Grey Hair and Is It Reversible?

The Library of Congress tells us that your chances of going gray increase about 10-20% every decade after the age of 30, although the medical community still doesn't largely understand why this occurs.

Exactly how this occurs is a different matter, though. Here’s the situation in a nutshell (we know you’re busy):

Melanin is a pigment polymer that gives your skin and hair its natural color, which is delivered via specialized cells called melanocytes. In the instance of hair, these cells are located at follicles and inject color as the shaft grows.

At some point, these melanocytes slow or stop their pigment production, leading to gray, colorless hair.

While the gene for gray hair seems to have been recently identified, there is no cure for the condition, outside of coloring products like those from Just For Men.

In the instance of Control GX Shampoo, exactly which ingredients does it use to deliver results—and are they clinically proven to work?

How Do Control GX’s Ingredients Gradually Reduce Grey Hair?

While we didn’t encounter a product label during our research, Walmart.com listed the following ingredients for Control GX Shampoo:

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.

Like most hair care and coloring products, authoritative websites report that the majority of Control GX’s ingredients work as surfactants, emollients, emulsifiers, thickeners, pH regulators, hair dye agents (N,N-Bis (2-Hydroxyethyl)-p-Phenylenediamine Sulfate), enzymes (1,2,4-Trihydroxybenzene), and preservatives.

Just For Men tells us that Control GX’s formulation also contains a patented blend of molecules that break when massaged and exposed to air, releasing small amounts of the complex and trapping it in the hair shaft every time you shampoo.

In layman’s terms, Control GX is essentially hair dye in shampoo form that, instead of coloring all your hair at once, deposits molecules over time, which then build up and hide gray over the course of several weeks.

Will Control GX Shampoo Cause Any Side Effects?

Some Just For Men customers have reported chemical burns and allergies from the use of the company’s products, so they mandate that you perform a preliminary 48-hour skin allergy test with Control GX, according to directions, before full-scale use.

The company also notes that Control GX shouldn’t be used if you’ve experienced a reaction to other hair color products, if you have a rash or your face, or an irritated, sensitive, or damaged scalp.

Temporary black henna tattoos may increase your risk of allergy. In rare cases, the use of hair color has been associated with temporary and permanent skin depigmentation (lightening).

Just For Men tells us that Control GX Shampoo can be used on any shade of hair, although it’s advertised as ideal for light brown to black hair. You can also use it with other hair care products, but not on hair that has been lightened, bleached, highlighted, or colored.

Pro tip: Many customer reviews we read also mentioned that—like other hair dyes—Control GX has a tendency to stain fingernails, the shower area, and towels. As a result, they recommend massaging it in using your palms, thoroughly rinsing the shower area when you’re finished, and using dark towels to dry off.

How Much Does Control GX Shampoo Cost?

A 5 fluid ounce tube of Control GX Shampoo (enough to last for approximately six weeks, according to the manufacturer) is available at most retailers who carry Just For Men products for between $8 and $9.

It can also be purchased directly through the company for $8.49, with free shipping on all orders over $14.

Money-saving tip: At the time of writing, you could also obtain a $2 off coupon on the Just For Men website.

In addition to Shampoo, Control GX also offers a 2-in-1 shampoo and conditioner that contains additional agents for easier combing, softness, and manageability, for the same price.

Are customers reporting a solid return on investment at this price?

Control GX Shampoo Reviews: Are They Good?

On the Just For Men website, Control GX had an average rating of 4.5 stars based on 300+ customer reviews. Most compliments referenced good coloring results, natural appearance, and ease of use, while what few complaints there were often related to messiness and minor nail discoloration.

What it similar elsewhere online?

We also encountered nearly 50 Amazon customer reviews for Control GX, who had given the shampoo an average rating of 3.7 stars. There, most of the compliments and complaints matched those on the Just For Men website.

According to Amazon’s Questions & Answers section, a couple of customers replied that they didn’t recommend Control GX for super short hair (1/4 inch or less). Another reviewer mentioned that you might want to use gloves to avoid staining your fingernails.

From a company perspective, the Just For Men lineup is manufactured by Combe Incorporated based out of White Plains, NY. They had an A+ rating with the Better Business Bureau and only two complaints as of 2/14/16, which referenced product formulation and side effects.

Does all of this mean you should spend your hard-earned money on Control GX?

Are the Gradual Results Provided By Control GX Shampoo the Way to Go?

While we didn’t encounter any products using the exact same formula as Control GX during our research, or those that were offered in shampoo form, HairFinder tells us that most dyes that promise to gradually reduce gray hair use metallic salts, which:

“… react with the sulfur in the protein chains of the hair to create a natural looking color in the hair over a period of repeated exposure.”

Perhaps the best-known gradual metallic hair dye is Grecian Formula, although Just For Men’s Touch of Grey treatment seems to deliver similar results. And both of these options are likely available locally for about the same price as Control GX.

How to decide? Just like anything else we choose to put on our body, the ‘best’ way of getting rid of grey hair will be based on your hair color (including level of grey), your hair cut (as well as any hair loss you’ve experienced), your skin type, and dozens of other personal factors.

In other words, there’s no way to know without giving it a try. Fortunately, Just For Men stands behind Control GX Shampoo with a 100% satisfaction guarantee, as might the retailer you purchase it from.

This way, you might not lose much more than a little of your time (and perhaps return shipping charges if you’re not near a retailer) for giving Control GX a shot and end up dissatisfied.

  • Read instructions

    I did not read the reviews before use. Although I've been using Just For Men for years, I tried Control GX for the first time. My hair is too short, and I have brown blotches on my head. Also, skin irritation. I have a job interview in the morning, but I don't think I'll go. What to do?

    Bottom Line: Yes, I would recommend this to a friend

  • Results of using Just For Men Control GX

    I was happy to read so many success stories, but mine is not one. Everything about the product ads was true except the results. My attempt was not to rid gray but to get an even color of gray. However, the product turned my hair a horrible Fluorescent Blue in only two applications. I had no problem with staining of the shower or myself, but I did follow instructions. I loved the texture (body) and shine on the first application, but all went downhill after that.

    I have been in hiding now for about a week, and blue is slowly getting grayer gradually. The ad sounded like a perfect option to even my uneven gray hair, and I have never done anything to my hair past. Terrible experience for me. Just please be aware if you chose to use this product.

    Bottom Line: No, I would not recommend this to a friend

  • Not good

    I used this product and noticed hair loss and not good hair covering of grey. I used it as instructed and maybe I'm sensitive. I have used Just For Men hair coloring and have no problems. I would advise to be careful and let others know of problems.

    Bottom Line: No, I would not recommend this to a friend

  • Beware: you could get bald in no time!

    It works, in a sense that you get rid of gray hair, and it looks ok. However, you may start losing hair in dramatic fashion! I think I lost 70% of hair on top by using one and a half tubes of Control GX for three months. Hopefully, it will start growing again. This was a BIG mistake.

  • Dramatic hair loss

    The product does change the color of my hair, but it is also making my hair fall out in dramatic fashion. I had to stop using the product and now have to figure out how to detox my scalp and my body from the chemicals that caused the fallout. I have no idea if the lost hair will ever grow back.

    If anyone has had any success in growing back the lost hair, then please share. Starting to get depressed.

  • Major hair loss

    • By Robert U.,

    • Verified Reviewer

    I am 52 years old and have been fortunate to have always had a thick, full head of hair with zero hair loss. I started on this to get rid of my grey. First, the shampoo feels really greasy and more like a conditioner than shampoo. It got rid of my grey, but within a month, I had lost approximately 50% of my hair. All my friends were asking me if I was sick. I immediately stopped using it and about 2 months later I had my thick grey hair back. I've used other dyes before and never lost hair. My recommendation would be to stay away from this stuff.

    Bottom Line: No, I would not recommend this to a friend

  • Ideal - if your aim is baldness!

    I have used GX for around three months, approximately 1 tube a month.

    Yes, it has reduced my grey hair, BUT it has reduced all my hair. I have suffered major hair loss with using this product, and only HOPE that it will grow back now that I have stopped.

    I would NOT recommend using this product. It is loaded with chemicals that, in the end, remove ALL your hair!

    Bottom Line: No, I would not recommend this to a friend

  • Lighten my hair

    • By Russell S.,

    • Verified Reviewer

    I have dark brown hair with some gray hairs starting to pop up on both sides of my head. Tried Control GX and it had turned my dark brown hair to a medium brown with a tint of red. My friends had asked me why my hair is much lighter than it was. Control GX would be a good product if it would come in black, dark brown, medium brown, etc.

    Bottom Line: No, I would not recommend this to a friend

  • This doesn't really do nothing for my gray hairs

    This product is not for African American people because I tried it for a few weeks and it doesn't really work for me. Maybe I should leave it in a little bit longer, I don't really know, but I don't think that I would buy this again.

    Bottom Line: No, I would not recommend this to a friend

  • Works, but be prepared for major hair loss

    • By Gerald K.,

    I began using this product over 1 year ago, and have now stopped. It took about 4 weeks to see results, but was really effective at controlling grey hair. But after a few months, I noticed my hair was thinning. At first, I thought it was simply due to aging. But then realized after about 6 months, everyone was saying I'm going bald. My drain began getting clogged every few weeks with hair, which was highly unusual. I decided to stop using it. Been waiting, but haven't noticed my hair returning yet. Does anyone else know of a replacement product that won't thin your hair?

    Bottom Line: No, I would not recommend this to a friend

  • 2 for 1

    • By Mustafa H.,

    • Length of Use: 6–12 months

    I agree that trying to get the results on the package is more difficult now that it's a 4 oz and not a 5 oz tube for the same price. So I had this idea where I removed the cap of the empty tube, grabbed a different bottle of shampoo (I believe I paid about $3 for an 18 oz bottle) and I slowly squeezed the full bottle into the tube until it was full again. I expected it to come out the same color that went in (light green) but it came out jet black. I used it until it was all gone again and noticed that I was able to maintain the color I had. Not sure this will work for others, I feel I got more of my money's worth.

    Pros and Cons:

    • Innovative
    • Want more for less

    Bottom Line: Yes, I would recommend this to a friend
