The 9 Best All-Natural Shampoos for Men, Tested by Grooming Experts

Sure, everybody's heard of a two-in-one shampoo and conditioner. Maybe you've even tried a three-in-one option with added formulation for the body. But Dr. Bronner's looked at those, scoffed, and added 15 more. That's not a typo; this is an 18-in-one product—and an effective one at that. Sure, it sounds a bit crazy using the same soap you wash your body with for your dishes, but I can confirm that this stuff is effective across the board.

This is especially true for hair, as it left my hair looking shiny and feeling ultra-hydrated. That being said, I recommend (as do the instructions on the bottle) diluting the liquid with a three-to-one water/soap ratio (pro tip: you can also cut it with coconut oil for added hydration). This not only will help minimize the strength of the initially overpowering scent, but also keep the bottle lasting forever.

It turns out, soy works as an excellent meat replacement as well as a substitute for harsh chemicals often found in standard shampoos. Plus, soy proteins are known to stimulate and strengthen hair follicles to help promote not only healthier but thicker hair. This natural shampoo utilizes the versatile ingredient to its fullest potential by combining it with Indian cress and watercress for added volume and health. This is in addition to it being verified by the Environmental Working Group to ensure there are no ingredients of concern.

If you're somebody who prefers bar soap to body wash, you'll probably also dig a shampoo bar, although this all-natural option from Church California is stellar enough to make any liquid devotees curious. For those who have never tried one, the major benefits of using bar shampoo are that they're more eco-friendly (read: no plastic container) and more travel-friendly because they're compact with no risk of leakage.

Church California's bar offers these and more. It's devised largely of fermented rice water, which helps promote hair growth and hair density. Not to mention, this bar lasts forever (seriously, I've got weeks out of just one of these 3 oz bars). Add in a wonderful woodsy yet somewhat floral aroma, and this shampoo bar is a true winner. Only minor gripe with the bar is that our fine-haired testers found it generally more effective than our thicker-haired testers, noting that it can leave a slightly oily feel.

This scalp-cleansing natural shampoo is led by three powerful ingredients: apple amino acids, baobab oil, and old reliable glycerin. The trio works in tandem to break down grime and oil, hydrate the scalp, and boost hair health. Glycerin is one of the most effective hydrators, which helps strengthen the scalp’s moisture barrier. This is boosted by baobab oil’s ability to rebalance the scalp microbiome, further improving overall scalp health, while apple amino acids gently clear dirt and oil.

This left my scalp with that tingly, fresh feeling each wash, as well as hair soft and strong. If you’re someone who washes your hair every day, however, I wouldn’t use this that often. I found its intensive scalp reset can be drying if used several days in a row. But for three or four washes a week, it’s perfect.

Dr. Bronner’s 18-in-1 too intense/overwhelming for you? Every Man Jack’s classic 2-in-1 shampoo and conditioner is a great scaled-back option where you’ll still save time and money by not buying a dedicated conditioner. There’s glycerin to hydrate, soy to strengthen, and tea tree to thicken—not to mention the scent.

This convenient shampoo and conditioner has one of those great, earthy scents that Every Man Jack has become known for. The tea tree gives it a fragrance that smells like waking up in a rainy northwest forest in the best way possible.

Highland The Wash features an all-star line-up of natural ingredients that boost softness and texture, including lentil seed, quinoa seed, and cicer seed. There are also known hydrators like meadowfoam flower, glycerin, and hyaluronic acid. Plus, there’s caffeine and rosemary oil, which can help hair look and feel fuller.

When it comes to everyday washes, this is my go-to. It does everything you want a shampoo to do—cleanse and boost hair health—without stripping the scalp. The scent is nice, but subtle so it never clashes with my cologne or other fragrances, either.

Native offers a natural alternative that’s as convenient as Every Man Jack’s 2-in-1, effective at supporting scalp health as Act + Acre, and cheaper than both. And in the case of the latter, Native is less than half the price. This option relies on salicylic acid to remove oil buildup, while avocado oil moisturizes and soothes. It’s pretty lightweight, but just like Act + Acre, I wouldn’t use it every single day. This will likely lead to irritation or dryness.

Still, Native’s 2-in-1 is sulfate-free, silicone-free, paraben-free, and dye-free, so you can wash in confidence, and the refreshing mint scent is a nice touch. I also find it to be one of the more expansive lathers on this list; I only need about a nickel-sized amount to wash my hair, which, to be clear, I’ve been growing out for eight months. If you have shorter hair, I doubt you’d need more than a dime-sized amount.
