How to Swap to Non-Toxic shower caps:

Here's how to swap to non-toxic shower caps:

What to know about shower caps

Most shower caps are made from synthetic plastics like PVC or polyester, often with elastic bands and waterproof coatings. Since a shower cap sits directly on your head and is used in a warm, steamy environment, the materials it's made from matter more than you might think.

  • Heat and steam can increase what synthetic materials release, so a cap worn in a hot shower gets more attention than one sitting in a drawer.
  • Shower caps used daily or several times a week deserve more consideration than ones used occasionally.

Check what your shower cap is made of

Look at the label or packaging of your current shower cap to see what materials it's made from. Many conventional shower caps are made from PVC (vinyl), which can contain phthalates and other chemical softeners.

  • If your shower cap has a strong plastic smell, that's a sign it may be made from lower-quality synthetic materials.
  • Check if the cap has a fabric lining — caps with a natural fiber lining like cotton reduce direct contact between plastic and your hair and scalp.

Use your current shower cap more safely

If you're not ready to replace your shower cap right away, a couple of small changes can help. Reducing heat exposure and improving airflow around the cap can make a difference.

  • Let your shower cap air out between uses instead of storing it in a sealed bag or damp corner — this helps reduce moisture buildup and any off-gassing.
  • If your cap is made of PVC or smells strongly of plastic, try keeping it out of direct contact with very hot water and steam by putting it on after you step out of the main stream.

Choose a cleaner shower cap

Look for shower caps made with natural fiber linings like organic cotton or silk, with a waterproof outer layer that is free of PVC, phthalates, and PFAS. Simpler materials and fewer chemical treatments make for a better cap.

  • Choose caps with a PEVA or TPU waterproof layer instead of PVC — and bonus points if the lining is organic cotton, silk, or another natural fiber.
