Could My Itchy Skin Be Caused by Laundry Detergent?

You’ve tried everything, cutting back on sunscreen, switching makeup brands, changing your soap... and still, the itchiness lingers. But then, one morning, just as you opened your eyes and remembered the laundry piling up, it hit you: Could it be the laundry detergent?

Turns out, yes. It absolutely could.

How Laundry Detergent Can Affect Your Skin

Most people don’t think twice about their detergent.

In fact, we often use way too much, assuming that more soap means cleaner clothes and a fresher scent.

But here’s the truth:

Laundry detergents often contain a mix of fragrances, dyes, and harsh chemicals that stay on your clothes, towels, and sheets, making contact with your skin 24/7.

If your washing machine isn’t rinsing thoroughly, or if you're overloading it with too many products, those chemical residues stay right where you don’t want them: on your skin.

What’s Really in That Detergent?

The main job of detergent is to strip grease and dirt.

But when harsh surfactants and synthetic fragrances remain in the fabric, they may also strip your skin's natural oil barrier, leading to irritation or full-blown Allergic Contact Dermatitis.

Especially vulnerable:

• People with sensitive skin

• Babies and young kids

• Those prone to eczema or dry skin conditions

Clue for parents: If your child has itchy skin everywhere but under the diaper or underwear, it could be your detergent.

Common Skin Reactions to Laundry Detergent

Watch for these signs that your detergent might be irritating your skin:

• Red or itchy patches

• Dry, cracked, or burning skin

• Hives or small rashes

• Heightened sun sensitivity

How to Prevent Skin Irritation from Laundry Products

There are several simple and natural ways to reduce or eliminate detergent-related irritation.

1. Rinse Twice

Many detergents leave a film on clothing. A second rinse cycle helps remove excess chemicals.

2. Use Less Detergent

Most people use more than needed. Check the label and measure properly.

3. Choose Fragrance-Free & Dye-Free Products

Ideal for sensitive skin, especially for babies and kids.

Natural Ways to Clean Clothes

If you prefer a more holistic lifestyle, here are a few skin-friendly options:

1. Baking Soda or Vinegar

Add ½ cup of baking soda OR apple cider vinegar (not both) to your laundry for a natural cleanse and softening effect.

2. DIY Laundry Detergent

Use a blend of:

• Borax

• Washing soda

• Castile soap (olive oil-based)

3. Pre-Treating Stains Naturally

Mix baking soda, vinegar, and washing soda. Let it sit for 15–30 minutes before washing.

4. Clean the Washing Machine

Run an empty hot cycle with ½ cup baking soda and vinegar to remove buildup and residue.

5. Use Dryer Balls Instead of Sheets

Dryer balls made from wool, rubber, or silicone reduce static and avoid chemical softeners.

Other Possible Triggers Beyond Detergent

If switching your laundry products doesn’t solve the problem, consider other common irritants:

• Nickel (in jewelry, buckles, coins)

• Cosmetics, deodorants, hair dyes

• Topical antibiotics or oral medications

• Preservatives like formaldehyde

• Perfumes, flavorings, mouth rinses

• Certain plants, including poison ivy and mango

• Sunscreens that cause photoallergic reactions

The condition is called Allergic Contact Dermatitis, and a dermatologist can run tests to pinpoint the cause.

What Happens If You Ignore the Problem?

If you don’t address the underlying trigger, like a harsh detergent, your skin may develop secondary infections.

Persistent scratching can cause open wounds, which invite bacteria or fungi.

This creates a cycle of discomfort that may require medical treatment.

If your skin is acting up and you haven’t looked into your laundry routine, now’s the time.

Start with:

• A fragrance-free, dye-free detergent

• Rinsing clothes twice

• Cleaning your washing machine regularly

And if you're still unsure, consult with a board-certified dermatologist to get clear answers.
