Our top pick is the **[Old Spice Swagger 2-in-1 Shampoo and Conditioner](https://twelvetabs.com/reviews/best-shampoos-for-men/#pick-1)**. It won the main TwelveTabs search we ran for this guide, "best shampoo for men", out of 68 Amazon listings. It is a 2-in-1 shampoo and conditioner made for men, in a 21.9 fl oz pump bottle with a cedarwood lime scent, and it suits anyone who wants one bottle that does both jobs. Want hair that looks fuller? The **[Cremo Thickening Shampoo](https://twelvetabs.com/reviews/best-shampoos-for-men/#pick-2)** won our thickening search. If you prefer a natural formula and a separate conditioner, the **[Dr. Squatch Natural Shampoo and Conditioner Set](https://twelvetabs.com/reviews/best-shampoos-for-men/#pick-3)** won our natural search. And for a big bottle of 2-in-1 with a tea tree and cedar scent, the **[Every Man Jack Tea Tree 2-in-1](https://twelvetabs.com/reviews/best-shampoos-for-men/#pick-4)** comes in a 24 oz size. ## How to choose a shampoo for men Men's shampoo is mostly shampoo with a different scent and a different label. What matters is your hair and your routine, not the word "men" on the bottle. Look at these four things. - **Your hair type.** The American Academy of Dermatology (AAD) says to choose hair care products made for your hair type, from fine and straight to thick and tightly coiled. A thickening shampoo aims to add body to fine or flat hair. A heavier formula suits thick or dry hair better. - **How often you wash.** The AAD says to wash based on how often your hair gets dirty or oily. If you have straight hair and an oily scalp, you may want to shampoo every day. If your hair is dry, textured, curly or thick, shampoo when needed. Daily washers use a lot of shampoo, so bottle size matters more for them. - **2-in-1, or shampoo plus conditioner.** A 2-in-1 saves a step. The AAD recommends conditioner after washing, because it moisturizes and detangles hair and makes it easier to manage. It also says dry or curly hair needs conditioner along the whole length, while fine or straight hair needs it only on the ends. If your hair is long, dry or curly, a separate conditioner gives you more control than a 2-in-1. - **Where the shampoo goes.** The AAD's advice is to put shampoo on your scalp, not the whole length of your hair. That cleans away oil and built-up product without drying your hair out too much. One more thing: a thickening shampoo changes how your hair looks and feels. It is not a treatment. If you are losing hair, a board-certified dermatologist is the person to see, as the AAD itself advises for hair and scalp conditions. ## Our picks in detail ### 1. Old Spice Swagger 2-in-1 Shampoo and Conditioner: best overall **Why it made the list** - It won our main search, "best shampoo for men", from 68 listings. - It is a 2-in-1 shampoo and conditioner made for men, so one bottle covers the whole wash. - It comes in a 21.9 fl oz bottle with a pump, and its listing says it is for all hair types. - The cedarwood lime scent is designed for daily hair care. **Drawbacks** - A 2-in-1 gives you less control over conditioning than a separate conditioner, which matters more for long, dry or curly hair. This is our inference from the AAD's advice, not something the listing says. - The Swagger scent is strong by design. If you want a light or unscented shampoo, look elsewhere. **Watch for this:** the same Swagger 2-in-1 is also sold as a twin pack of two larger 29.2 fl oz bottles. It is the same formula under a second listing, so check which one you are buying. **Skip it if** you like to condition separately or want a shampoo with little or no scent. ### 2. Cremo Thickening Shampoo: best for fuller-looking hair **Why it made the list** - It won our search for "best thickening shampoo for men", from 58 listings. - Its listing says it is made as a thickening shampoo for men. - It has a juniper and eucalyptus scent and comes in a 16 fl oz bottle. **Drawbacks** - It is a shampoo only, so you need a separate conditioner. - A thickening shampoo works on how hair looks and feels. It does not treat hair loss. **Skip it if** you want a single bottle that shampoos and conditions, or if your hair is already thick. ### 3. Dr. Squatch Natural Shampoo and Conditioner Set: best natural pick **Why it made the list** - It won our search for "best natural shampoo for men", from 64 listings. - Its listing says it is made as a natural shampoo and conditioner set for men. - You get a matched shampoo and a separate conditioner, two 11 fl oz bottles, so you can condition only the parts of your hair that need it. **Drawbacks** - Each bottle is 11 fl oz, smaller than our other picks, so daily washers will run through it faster. - Two bottles means two steps in the shower. **Skip it if** you want the quickest possible routine or the biggest bottle. ### 4. Every Man Jack Tea Tree 2-in-1: best big bottle **Why it made the list** - It was a runner-up in our natural search. - It is a 2-in-1 shampoo and conditioner for men with a tea tree and cedar scent. - It comes in a 24 oz bottle, the largest single bottle among our picks. **Drawbacks** - It surfaced in our natural search, but its listing does not say it is a natural formula. Do not buy it for that reason. - As a 2-in-1, it has the same conditioning limits as our top pick. **Skip it if** a natural formula is the reason you are shopping. ## What we left out, and why Our three searches returned 190 Amazon listings. We kept four, one for each need. - **Old Spice Swagger 2-in-1, twin pack.** A runner-up in our main search, but it is the same formula as our top pick in larger bottles. - **Dove Men+Care 2-in-1, Sandalwood and Cardamom.** A runner-up in our main search. It is another 2-in-1 for men with a warmer scent, and it would duplicate our top pick's need. - **OGX Thick and Full Biotin and Collagen Shampoo** and **L'Oreal Paris Thickening Sulfate Free Shampoo.** Runners-up in our thickening search. Neither listing is made for men, and Cremo covered the need. - **method men 2-in-1, Sea and Surf.** A runner-up in our natural search. Its listing mentions plant-based ingredients but does not call it a natural formula, and it would duplicate the 2-in-1 need. - **Dove Men Dandruff Defense 2-in-1.** It turned up in our natural search, but it is a dandruff product, not a natural one. Dandruff is a scalp condition, and this guide does not cover it. Wirecutter has no guide to men's shampoo. Its general shampoo guide picks by hair type rather than for men, so there is no Wirecutter top pick to place in our table for this guide. ## Questions people ask ### Is men's shampoo different from women's shampoo? Mostly in scent and packaging. The AAD's advice is the same for everyone: pick a product made for your hair type and wash as often as your scalp needs. A men's label is a reasonable place to start, not a requirement. ### Is a 2-in-1 shampoo and conditioner good enough? For short hair and a quick routine, often yes. The AAD recommends conditioner after washing, and says dry or curly hair needs it along the whole length. If that sounds like your hair, a separate conditioner, like the one in the [Dr. Squatch set](https://twelvetabs.com/reviews/best-shampoos-for-men/#pick-3), gives you more control. ### How often should men wash their hair? It depends on your hair and scalp. The AAD says people with straight hair and an oily scalp may want to shampoo every day, while people with dry, textured, curly or thick hair can shampoo when needed. For what goes on after washing, our [men's hair products guide](https://twelvetabs.com/reviews/best-hair-products-for-men/) covers pomades, creams, gels and powders. ### Will a thickening shampoo regrow hair? No. A thickening shampoo is made to change how hair looks and feels. For hair loss, see a board-certified dermatologist. ### How did TwelveTabs choose these shampoos? TwelveTabs ranked the Amazon listings for “best shampoo for men”, “best thickening shampoo for men” and “best natural shampoo for men”, read the pages of 10 finalists and named a winner in each search. From those 190 listings, we kept the four that each suit a different need, as of September 25, 2026. We checked the advice against American Academy of Dermatology and Wirecutter. AI wrote this guide from it. Listings change, so check the details on Amazon before you buy. ## How we researched On September 25, 2026 we ran three live TwelveTabs searches of Amazon: “best shampoo for men”, “best thickening shampoo for men” and “best natural shampoo for men”. Together they returned 190 listings. TwelveTabs shortlisted 10 from each search, read the listing pages of 10 finalists and named a winner and its runners-up in each. We kept four that each suit a different need. AI wrote this guide from that research. Listings change: we read them on September 25, 2026, and a formula, size, seller or stock may differ today. A thickening shampoo is not a hair-loss treatment. ### Sources - [American Academy of Dermatology: Tips for healthy hair](https://www.aad.org/public/everyday-care/hair-scalp-care/hair/healthy-hair-tips) - [Wirecutter: The Best Shampoos](https://www.nytimes.com/wirecutter/reviews/best-shampoo/)
