How to Swap to Non-Toxic purple shampoos:
Here's how to swap to non-toxic purple shampoos:
What to know about purple shampoo
Purple shampoo is a toning product designed to neutralize brassy or yellow tones in blonde, silver, or highlighted hair. Because it's used regularly and applied directly to your scalp and hair, the formulation matters. Welpr looks at the full ingredient list — including the purple pigments, fragrances, preservatives, and surfactants — to make sure nothing unnecessary is sitting on your skin.
- Purple shampoos often contain synthetic fragrance, harsh sulfates, and preservatives that wouldn't pass Welpr's standards.
- Since this product contacts your scalp repeatedly, it's worth more attention than a product you'd use only once in a while.
Review what you already use
Check whether your current purple shampoo meets Welpr's standards by scanning its ingredient label. Open the Welpr Personal Care and Cosmetic Scanner, take a photo of the back label, and it will flag any concerning ingredients for you.
- Look for "fragrance" or "parfum" on the label — if it's listed without further detail, it likely contains undisclosed synthetic fragrance.
- Check your purple shampoo first if you use it weekly or more, since frequency of use increases what your scalp absorbs over time.
Use your current purple shampoo more carefully
If you're not ready to switch yet, small changes in how you use purple shampoo can reduce what your scalp absorbs. Since it's a rinse-off product, limiting contact time is the simplest adjustment you can make.
- Avoid leaving purple shampoo on your hair longer than needed — apply, tone, and rinse promptly rather than letting it sit for extended periods.
- Use it only as often as your hair actually needs toning, which for most people is once or twice a week rather than every wash.
Choose a cleaner purple shampoo
Look for purple shampoos with simple, transparent ingredient lists. Cleaner options use gentle plant-based surfactants, skip synthetic fragrance, and rely on safer pigments. Certifications like EWG VERIFIED™ or MADE SAFE® are a good sign, but Welpr still reviews the full formula.
- Choose formulas that are fragrance-free or scented only with essential oils, use gentle surfactants instead of harsh sulfates, and avoid parabens, PEGs, and phthalates.
