6 Best Thickening Shampoos for Men to Fight Thinning in 2024

You’ve heard it before— ”This product will definitely make your hair thicker,” or “Take these pills. They’ll make your hair grow!” Although some of them work to varying degrees, you either have to take it continually to see results or undergo some sort of procedure to combat hair loss. Or, you can simply use the best thickening shampoos for men and see results you’re happy with.

A mere shampoo can’t reshape the world, but it can promote hair growth and make your hair appear shinier, stronger, and thicker. It’s not magic but rather a combination of tested ingredients, including some natural ones, like biotin and rosemary, that invigorates the scalp and thickens each individual strand of hair.

A hair-thickening shampoo for men is a must if you notice that your hair has been thinning, your hair is naturally fine, or you’re simply looking for a volume boost.

The 6 best thickening shampoos for men are below.

Key Takeaways 

For this review, I began by poring over hundreds of photos, customer reviews, and even my own shower until I whittled it down to the 6 finalists you see on this list. Overall, the best hair-thickening shampoo for men is Redken Volume Injection Shampoo because it’s packed with a proven volume-boosting complex, adds texture in addition to volume, and provides salon quality at an approachable price point.

For a more natural shampoo that uses rosemary and nettle leaf to cleanse and volumize, look no further than Bondi Boost HG Shampoo.

Why it’s great: Formulated with a 1% filloxane bodifying complex, this shampoo strengthens each strand of hair from the inside out to add instant volume. In addition to making hair shiny and full, it adds texture, something thinning and/or fine hair often lacks. Even if you have an oily scalp, it deeply cleanses the hair without overstripping to revitalize limp, lifeless hair into something you’re proud of.

Who is this for? A solid choice for guys looking for salon-quality results at an approachable price point.

Flaws but not deal-breakers: Unfortunately, this hair-thickening shampoo for men does contain alcohols and sulfates, but it is formulated with a balanced pH and softening polymers that provide volume without stripping the hair.

Scent: Unscented | Material Feature: Paraben-free | Size: 10.1, 33.8 oz | Form: Liquid | Hair Type: Fine, flat hair

Why it’s great: This hair-thickening shampoo for men is worth the splurge if you’re looking for plump, strong hair to replace your limp locks. From the first use, you’ll notice a volume boost. It uses fiber body and hyaluronic acid to remove buildup, reduce hair breakage, and add weightless volume and hydration, all while protecting hair from external aggressors. It also tames frizzy hair—a nice plus.

Who is this for? A good choice for guys who fall on the luxury side but want a product that actually boosts thinning hair.

Flaws but not deal-breakers: It’s expensive, but a little goes a long way. Most find that this shampoo is worth it.

Scent: Floral | Material Feature: Paraben-Free | Size: 8.5 oz | Form: Liquid | Hair Type: Fine, thinning hair

Why it’s great: If you love the smell of Moroccanoil products, then you’ll love this hair-thickening shampoo for men. It has a light and clean signature scent that garners compliments on top of leaving hair lush and soft.

It uses body-building linden bud extract to gently cleanse and provide weightless volume. The feel of the shampoo itself is rather rich, but you’ll be pleasantly surprised that the nutrifying argan oil doesn’t weigh the hair down a bit.

Who is this for? The perfect choice if scent and fluffy, lightweight hair with some bounce is what matters to you.

Why it’s great: Hair is bigger in Texas, so it’s safe to assume that this Dallas Thickening Shampoo will do the trick. Thanks to biotin, which improves keratin infrastructure, and provitamin B5, which intensely hydrates, hair will feel softer, shinier, and fuller. Even if your hair type is fine, it won’t get weighed down and instead should be light and bouncy. It smells good, too, though the somewhat spicy scent is mildly divisive.

Who is this for? If traditional shampoos seem to weigh you down, then this option is ideal for your thin, fine hair that gets oily quickly.

Flaws but not deal-breakers: This hair-thickening shampoo for men is on the pricey side, but it definitely does what it says. It also offers good value.

Scent: Crisp fresh | Material Feature: Vegan, paraben, sulfates, cruelty-free | Size: 2, 8.5 oz | Form: Liquid | Hair Type: Thin, fine hair

Why it’s great: I’m not typically a proponent of drugstore shampoos, but this Pantene product has clearly undergone a recent upgrade. Unlike most of their products, which contain sulfates, this one is pretty clean.

Formulated sans sulfates, parabens, and dyes, this hair-thickening shampoo for men actually helps hair grow and does a pretty good job at volumizing the ones you’ve got. Both rice water and provitamin B5 strengthen the hair and provide gentle moisture, all while protecting hair from future damage.

Who is this for? For the guy who already loves Pantene (like my husband) and doesn’t want to break the bank to achieve fuller hair.

Flaws but not deal-breakers: This could leave your hair feeling dry, so remember to follow up with a hydrating conditioner.

Scent: Not listed | Material Feature: Paraben, sulfate, and dye-free | Size: 30 oz | Form: Liquid | Hair Type: All

Why it’s great: It may not be from a huge brand, but this hair-thickening shampoo for men does an excellent job at nourishing hair while majorly boosting its volume, all while focusing on natural ingredients to get the job done. Aloe vera, nettle leaf, and rosemary oil, a known hair growth ingredient are just a few of the phytoactive ingredients that decrease hair fall due to breakage, cleanse without stripping, and help to regrow hair.

Who is this for? If you prefer a more natural approach to hair care or have sensitive skin, then this may be the shampoo for you.

Flaws but not deal-breakers: It may make some hair types feel dry, so always remember to follow up with a hydrating conditioner and leave-in conditioner.

Buying Considerations for The Best Thickening Shampoos For Men

Price

You don’t have to break the bank to get your hands on the best hair-thickening shampoo for men, but I will say that you’ll get the best results when you purchase a high-quality brand. That’s why Redken is my top pick—it’s a salon brand that isn’t crazy expensive. The Pantene option on this list is good, but it probably isn’t the best. That being said, you can still get thickening results with any of the options on this list at various price points.

Cleansing Ingredients 

There’s a fine line between adequately cleansing the hair, overstripping it, and not getting hair clean at all. Usually, sulfates do the best job at cleansing, but they can dry out the hair. A few on this list actually contain sulfates but are well-formulated to counteract any dryness. If harsh cleansers are a no-no for you, there are other options on this list that adequately cleanse without this ingredient.

Plumping Ingredients

Now to the good stuff. The best hair-thickening shampoo for men contains plumping ingredients like biotin, linden bud extract, and even rosemary to stimulate the scalp, encourage hair growth, and thicken the hair follicle. Even filloxane does the trick. These are all solid ingredients to look out for to indicate that lusher locks are in your future.

How We Chose 

Plenty of shampoos claim to thicken thin, fine hair types. But sometimes, these claims just don’t seem to hold up. So, wherever possible, I chose shampoos from reputable brands that contain effective, well-known hair-thickening ingredients. I also sifted through hundreds of customer reviews, landing on my top 6 by choosing products that people rate highly and would likely buy again.

Company reputation: How often does a brand deliver perfect-quality goods on time and without the need to return? I prioritize companies and products that go the extra mile to make sure that their users are satisfied.

Customer reviews: Do consumers seem consistently satisfied with the quality and performance of the shampoo? If their hair seems well-cleansed and volume-boosted, then it makes the cut.

Value: Sure, a thickening shampoo might give hair a gorgeous body and bounce, but does it break the bank? Or, is it cheap and hardly does what it says? I am always sure to pick shampoos that thicken hair more than adequately while remaining within a range of approachable price points.
