How to Swap to Non-Toxic heat protectants:
Here's how to swap to non-toxic heat protectants:
What to know about heat protectant
Heat protectants are applied directly to your hair and often your scalp before styling, and they stay on without being rinsed off. Because they sit on your body during prolonged heat exposure, the ingredients they contain matter more than you might expect.
- Many heat protectants rely on synthetic fragrances, silicones, and preservatives that can build up on hair and come into contact with your scalp over time.
- Products you apply frequently and leave on rank higher in Welpr's risk framework, so a daily heat protectant deserves a closer look than something you use once a month.
Review what you already use
Check your current heat protectant using the Welpr Personal Care and Cosmetic Scanner. It takes a picture of your ingredient label and flags ingredients that may not meet Welpr's standards.
- Look at the ingredient list for "fragrance" or "parfum"—these often indicate undisclosed synthetic fragrance blends.
- If you use more than one heat styling product (a spray plus a serum, for example), scan the one you use most often first.
Use your current heat protectant more carefully
If you're not ready to replace your heat protectant right away, small changes in how you apply it can reduce unnecessary contact with your skin and scalp.
- Apply the product to mid-lengths and ends rather than spraying directly at your roots or scalp.
- Use the minimum amount needed for coverage—a little often goes further than you think, especially with spray formulas.
Choose a cleaner heat protectant
Look for heat protectants with simple, purposeful formulas. The best options skip synthetic fragrance, harsh preservatives, and unnecessary additives while still protecting your hair from heat damage.
- Choose fragrance-free options or products scented only with essential oils or plant extracts, and look for certifications like EWG VERIFIED™ or MADE SAFE® as a helpful starting point.
