Why Do Natural Deodorants Like Salt & Stone Cause Rashes?

If you’ve ever made the switch to a natural deodorant and ended up with red, itchy underarms, you’re not alone. A lot of people try brands like Salt & Stone only to find themselves dealing with irritation. Getting a rash from natural deodorant feels confusing. Isn’t natural supposed to be better for your skin?

Why Natural Deodorants Can Still Cause a Rash

Just because something is labeled "natural" doesn't mean it's gentle. Many natural deodorants contain ingredients that can actually trigger irritation. If you're dealing with a natural deodorant rash, there's usually a reason and understanding that reason can help you choose a better product for your skin.

Here are the most common causes behind rashes from products like Salt & Stone and other natural brands:

• Baking soda: A powerful odor fighter, but harsh on sensitive skin
• Fragrance: Even natural scents can trigger allergic reactions
• pH imbalance: Some formulas throw off your skin’s natural balance

Let’s break each one down so you know what to look out for and what to avoid.

Baking Soda: Effective, But Often Too Harsh

Baking soda, also called sodium bicarbonate, is a common ingredient in natural deodorants. It’s great at absorbing moisture and neutralizing odor. But there’s a catch: it’s alkaline, which means it has a high pH.

That matters because your skin’s natural pH is slightly acidic. When you apply baking soda regularly, it can disrupt that balance. Over time, this can lead to baking soda deodorant irritation, especially for people with sensitive underarms.

You might notice:

• Redness or bumps
• Burning or stinging
• Dry, flaky skin

If you’ve experienced any of this, you’re not imagining it. This is one of the top reasons natural deodorant causes a rash.

Fragrance: Natural Doesn’t Always Mean Safe

Brands like Salt & Stone often use essential oils and botanical extracts to create their signature scents. These may smell nice, but they can still trigger reactions. Just because something is plant-based doesn’t mean it’s non-irritating.

Fragrance is a leading cause of contact dermatitis. That’s the fancy term for a rash caused by skin contact with an irritating substance. In fact, for people with sensitive skin or allergies, even natural fragrances can be a major issue.

If you’ve had a Salt and Stone deodorant reaction, the fragrance might be to blame.

Look for Fragrance-Free Alternatives

To avoid this, choose a fragrance free natural deodorant. That means no synthetic scents and no essential oils. Just clean, gentle ingredients that won’t trigger a flare-up.

pH Imbalance: The Hidden Irritant

Even if a deodorant skips baking soda and fragrance, it can still cause problems if it messes with your skin’s pH. Your underarms have a thin protective layer called the acid mantle. It keeps bacteria in check and helps your skin stay calm.

When a product has the wrong pH too high or too low it can damage that layer. That’s when irritation, redness, and itchiness show up.

That’s why using a pH balanced deodorant is so important. It supports your skin’s natural barrier instead of disrupting it.
