How to Swap to Non-Toxic conditioners:
Here's how to swap to non-toxic conditioners:
What to know about conditioner
Conditioner sits on your hair and scalp for several minutes each use, giving its ingredients direct contact with your skin. Welpr focuses on what conditioners are made of — the fragrances, preservatives, and conditioning agents in the formula — because these determine how clean the product really is.
- Many conditioners rely on synthetic fragrance listed as "fragrance" or "parfum," which can contain undisclosed ingredients.
- Conditioning agents called quats are common in this category, and most are linked to irritation — Welpr only allows one gentle, plant-based option called behentrimonium methosulfate.
Check the conditioner you use now
Use the Welpr Personal Care and Cosmetic Scanner to check your current conditioner. It will flag ingredients that don't meet Welpr's standards, so you can see exactly where your product stands.
- Start with the conditioner you use most often — daily-use products matter more than occasional deep-conditioning treatments.
- If you also use a leave-in conditioner, check that one too, since it stays on your skin longer than a rinse-off formula.
Use your current conditioner more safely
If you're not ready to replace your conditioner yet, small adjustments can reduce how much contact it has with your skin. Focus on keeping the product on your hair rather than your scalp.
- Apply conditioner from mid-length to ends only, avoiding your scalp where skin absorbs ingredients more easily.
- Rinse thoroughly with cool or lukewarm water to remove as much residue as possible.
Choose a cleaner conditioner
Look for conditioners with simple, purposeful formulas. The best options skip synthetic fragrance, harsh preservatives, and unnecessary additives while still keeping hair soft and manageable.
- Choose fragrance-free formulas, or ones scented only with essential oils or plant extracts — avoid anything listing "fragrance" or "parfum" without full disclosure.
