The Best Aluminum-Free Deodorants That Actually Work

Most "natural" deodorants fail for one of two reasons: they don't control odor, or they make your armpits red and itchy. The good news is that both problems are easy to avoid once you know what to look for. Here are the aluminum-free deodorants that hold up, and how to pick the right one for your body.

First, what "aluminum-free" really means

Aluminum is the active ingredient in antiperspirants. It temporarily plugs your sweat ducts so less sweat reaches the skin. An aluminum-free deodorant doesn't stop sweat at all. Instead, it tackles odor, which comes from bacteria breaking down sweat on your skin.

That means two things:

• You will still sweat. That's normal and healthy. If wetness is your main problem, you need an antiperspirant (see our guide to clinical-strength antiperspirants).
• The goal is no smell, not no sweat. Judge a natural deodorant on whether you smell fine at 6 p.m., not on whether your shirt stays bone-dry.

How to choose an aluminum-free deodorant

1. Check for baking soda

Baking soda (sodium bicarbonate) is a great odor fighter, but it's alkaline, while healthy skin is slightly acidic. For many people that mismatch causes redness, itching or dark patches, sometimes weeks after starting. If that's happened to you, pick a baking-soda-free formula. Our sensitive-skin guide has more options.

2. Match the odor-fighter to your body

• Baking soda or magnesium: the classic natural approach, and effective for most people.
• Mandelic or lactic acid (as in Lume): keeps skin's pH low, where odor bacteria struggle. These formulas are often the most effective for strong odor.

3. Pick a format you'll actually use

Sticks are the easiest switch. Creams and gels apply with your fingers and often work better for sensitive or very hairy underarms. Sprays dry fastest.

4. Expect a short adjustment period

Many people feel sweatier for the first week or two after quitting antiperspirant, because their sweat ducts are no longer plugged. It settles down. Here's how to get through the switch without the smelly week.

The best aluminum-free deodorants

If you've never tried a natural deodorant, start here. Native is the easiest switch from a conventional stick because it feels like one: it's smooth, it isn't sticky, and the scents are genuinely nice. The one thing to watch for is baking soda. If you notice any itching after a week or two, move to the sensitive version below instead of giving up on natural deodorant altogether.

Lume is the pick when "regular" natural deodorants stop working by lunchtime. Because it uses mandelic acid instead of baking soda, it's also kinder to sensitive skin, so it solves both common complaints at once. It costs more than drugstore brands, but a little goes a long way.

You don't need boutique prices to go aluminum-free. Dove's version is gentle, widely available and usually far cheaper than boutique brands. It's a great way to find out whether aluminum-free works for you before investing in anything fancier.

Tips to make any natural deodorant work better

• Apply to clean, completely dry skin. Deodorant applied on damp skin rubs off faster.
• Give it a few extra swipes. Natural formulas need more product than conventional sticks to form an even layer.
• Reapply on long days. A travel-size stick in your bag solves most "it stopped working" problems.
• Wash with soap, not just water. Odor comes from bacteria, and a quick lather in the shower makes a big difference.
• Trim or shave. Underarm hair holds onto sweat and bacteria.
• Choose breathable fabrics. Cotton, linen and merino trap far less odor than polyester.
