How to Swap to Non-Toxic shampoos:

Here's how to swap to non-toxic shampoos:

What to know about shampoo

Shampoo is a product you use frequently, often daily or several times a week. While it's rinsed off, it still makes direct contact with your scalp, which is one of the more absorbent areas of skin on your body.

  • Welpr reviews every shampoo formula for synthetic fragrances, harsh sulfates, unnecessary preservatives, and endocrine disruptors like parabens and phthalates.
  • Even rinse-off products matter because repeated use over time adds up, especially for something applied directly to your scalp.

Review what you already use

Use the Welpr Personal Care and Cosmetic Scanner to check your current shampoo. It will flag any concerning ingredients so you can see how your product stacks up against Welpr's standards.

  • Start with the shampoo you use most often — if you rotate between a few, check the everyday one first.
  • Look for "fragrance" or "parfum" on the ingredient label — these terms can hide undisclosed synthetic ingredients.

Use your current shampoo more safely

If you're not ready to switch yet, small adjustments can help reduce what your scalp absorbs. This is especially worth considering for shampoos you use daily.

  • Rinse thoroughly for a little longer than usual to remove more residue from your scalp and hair.
  • Try spacing out washes by a day — less frequent use means less overall exposure to any ingredients you'd rather avoid.

Choose a cleaner shampoo

Look for shampoos with simple, purposeful formulas. Fragrance-free is the cleanest starting point, and if scented, the fragrance should come from essential oils or plant extracts rather than synthetic sources.

  • Certifications like EWG VERIFIED™ or MADE SAFE® are a good sign, but Welpr still reviews every formula individually — so look for the Welpr Approved label for the most confidence.
