Hair thickening shampoo is one of the many wonders of the haircare world. The concept of a bottle of miracle shampoo that promises to thicken and strengthen your hair is an appealing one. But does it really work?


As with the majority of cosmetic and haircare products, it really depends on the quality of the shampoo you've chosen. In other words, you get what you pay for. If you're hoping a thickening shampoo will help give your hair a boost, you should put down the shampoo bottle from the supermarket shelf and turn your eye to products made with clinically proven ingredients.


Here at Salt Grooming, we've spent years developing and formulating a collection of men's haircare essentials, including our own patented and clinically proven Thickening Shampoo. Along the way, we've tested and refined our formulas to make sure they deliver real results, so we know a thing or two about what makes these products work (and not work).


With that in mind, we're going to delve into your most commonly asked questions about thickening shampoos, including whether they work, how long it takes to see results, and what goes into these powerful bottles.

What Are Thickening Shampoos?

As the name implies, thickening shampoos create the appearance of fuller-looking hair and stimulate hair growth using ingredients that address the root causes of thinning hair.


Formulations will vary across products, but, for the most part, they'll contain active ingredients such as Vitamin B5, Caffeine, and other plant derivatives proven to target the scalp, promote hair growth, and maintain the integrity of healthy hair.


But the sole purpose of these products isn't just to accelerate hair growth. Just like all other shampoos, they’re formulated to help cleanse, condition, and nourish your scalp, too. 


Over the course of a day, your hair accumulates dirt, grime, and pollutants that can damage your hair and scalp. A thickening shampoo will cleanse your scalp and hair, help remove any buildup, and leave it looking and feeling fresh.

Key ingredients in high-quality Thickening Shampoos:

  • Ginkgo Biloba – stimulates healthy hair regrowth by improving scalp blood flow and circulation.
  • Saw Palmetto – blocks the production of DHT (hormone responsible for male pattern hair loss).
  • Red Clover Leaf – inhibits 5-alpha reductase enzymes (key contributor to hair loss).
  • Caffeine – counteracts balding effects of testosterone.
  • Vitamin B3 – increases hair fullness.
  • Wheat Protein – reduces oxidative stress damage to the hair and scalp.
  • Aloe Leaf – soothes and regenerates scalp skin cells whilst restoring hair.

Who Should Use a Thickening Shampoo?

Anyone and everyone can use a thickening shampoo.


If your natural hair lacks volume, a thickening shampoo will help to add some oomph to your trim by boosting your hair’s volume and thickness. 


Or if you take pride in your hair and want to give it the best care you can, a thickening shampoo is an excellent choice. Not only will it help to make your hair look fuller, but it’ll also give your scalp and strands extra nourishment for hair that looks better for longer.


But those who will benefit most from a thickening shampoo are those with fine, thin hair or men experiencing male pattern hair loss.


Our Thickening Shampoo contains ingredients that target the root of the problem and help re-energise the follicles. 


Saw Palmetto is a botanical extract that blocks the production of DHT, which is the hormone responsible for male pattern hair loss. By blocking these hormones and using ingredients to stimulate hair growth – like Caffeine, Red Clover Leaf, and Ginkgo Biloba – you'll start to see those thinning patches on your head fill in with thicker, healthier-looking hair.

Reasons Why You Might Be Experiencing Male Pattern Hair Loss

If you’re experiencing male pattern hair loss, it could be due to several factors. A few examples include:


• Genetics – genes that come with a predisposition to balding can be passed down through generations.


• Stress – prolonged stress has been linked to hair loss in both men and women.


• Hormone imbalances – hormonal imbalances can cause hair loss in men due to the levels of DHT, a hormone responsible for male pattern hair loss.


• Diet – poor nutrition can impact the health of your scalp and hair follicles, leading to male pattern baldness.


It's actually the most common cause of hair loss in men, with 16% of 18-29 year olds experiencing moderate to extensive hair loss. 


So, while it may be disheartening, know that you are not alone. With the help of scientifically-backed products, you can reduce the effects of male pattern baldness and fight back against hair loss.

Does Men's Thickening Shampoo Actually Work?

Yes, thickening shampoo really does work. It's not just another haircare fad – it's a clinically proven solution to improving the appearance of thin, flat, or balding hair.


Those ingredients we mentioned earlier? They work harmoniously to create a powerful formula that helps to stimulate hair growth from the follicles. 


The cleansing ingredients also play a big part in helping to thicken hair – new hair can't grow if there's build-up blocking the follicles, so keeping your mop squeaky clean is an important part of any hair revival plan.

The Science Behind the Ingredients

One of the main ingredients that power thickening shampoo is caffeine – a very effective and clinically proven stimulant in hair growth. 


Applying caffeine topically to your scalp or within a shampoo formula counteracts balding caused by the testosterone hormone. 


Testosterone can convert to another hormone called DHT (dihydrotestosterone), which can cause hair follicles to become damaged, resulting in hair loss. 


The caffeine’s job is to ‘block’ the effects of DHT and instead stimulate the growth of hair follicles, increasing the rate of hair growth.


But it’s not just caffeine that stimulates hair growth. Ginkgo Biloba is another key ingredient that you’ll find in our Thickening Shampoo, which also promotes healthy hair growth – it’s more scarce than caffeine but just as effective. This plant possesses great anti-oxidant characteristics that improve blood flow and circulation to the scalp. 


By increasing blood flow to the scalp and hair follicles, we’re also encouraging nutrients and oxygen to reach the scalp, helping the hair follicles grow longer hair.


Vitamin B3 is another renowned ingredient in the hair growth world, and you’ll find it in many haircare products, not just thickening shampoo for men. 


This is a really important vitamin for hair growth and overall health, aiding in improving blood flow to the scalp and encouraging nutrients and oxygen to stimulate the hair follicles.

How Else Can Men Make Their Hair Thicker?

You shouldn't just rely on the shampoo to do all the work for you, though. You can help the hair thickening process along by including a few other steps into your routine.


Firstly, ensure you get all the essential vitamins and minerals needed for healthy hair growth. B vitamins, especially biotin, are important for healthy hair. You can get these through supplements or from eating plenty of leafy greens, avocado, nuts, and seeds.


You could also use a scalp scrub every week to improve circulation and remove any dead skin cells that may be blocking your follicles. Just as you use a facial exfoliator on a weekly basis, you should give your noggin the same attention.


Buddying up your thickening shampoo with a thickening conditioner can also significantly help. These products will contain ingredients similar to the shampoo and work alongside it to help give your hair a thicker, fuller look.

What is the Best Thickening Shampoo for Men?

The results you see will, of course, largely be down to your hair type and genetics, but the product you use is really important, too. 


After having heard of many unsuccessful stories of tried and tested shampoos and unmet promises, we set out to create a shampoo that won't let you down.


As with all our cutting-edge formulations, we partnered with Britain’s leading cosmeceutical scientists to develop an advanced formula using clinically proven ingredients


Our Thickening Shampoo visibly thickens hair from the first wash, thanks to our powerful combination of ingredients. It cleanses, nourishes, hydrates, and stimulates the scalp whilst providing superior protection against damage and breakage.


It's not just us that think it's great, either – hear it from our customers:

“As a man in my 50's I tried this shampoo as a means of making my hair look thicker, I have since purchased this shampoo on several occasions, in fact it is now the only shampoo I use. My hair feels and looks considerably thicker and lustrous it is also kind to the scalp and I am able to use it daily. Would wholeheartedly recommend this product.”

"Makes a big difference to thin hair. Can recommend."

Rich Davies on Nov 09, 2022

“Really great product, the whole experience feels high quality. Lathers up nice and thick and makes the scalp tingle with the refreshing minty scent. Gives that satisfying slick feeling when you rinse out and hair looks super shiny and feels thick and healthy after. What I like most though is that my hair doesn't go fluffy after it dries which i find that pretty much every other shampoo I've tried does. Great work guys”

How Long Does Thickening Shampoo Take to Work?

A thickening shampoo aims to actually increase hair growth by stimulating the scalp and follicles, which results in thicker hair. A volumising shampoo is more for aesthetic purposes - it will create an illusion of thicker hair, but won't necessarily increase the thickness itself.

How Often Should I Use a Thickening Shampoo?

You should use your thickening shampoo every time you wash your hair, whether that be two times a week or every other day. Increasing the number of times you use the shampoo won't accelerate your hair growth; it has more to do with the period of time in which you use the shampoo and how your hair responds to it.

What's the Fastest Way to Get Thick Hair?

Switch out your regular shampoo for a thickening shampoo, like our advanced formula that visibly thickens your hair from the first wash. You can also style your hair to add more volume, like blow-drying your trim upside-down and using styling products.
