Lower PFAS concern for typical leave-in spray; no red flags identified, but brand does not disclose water-resistance treatment status.
DevaCurl MIST OF WONDERS is a hydrating leave-in curl spray with no known Teflon-type coating, Teflon-family coating, or waterproofing treatment. Hair sprays and leave-in products are not high-risk PFAS categories unless formulated with water-resistant or grease-resistant additives, which DevaCurl does not publicly claim.

The full breakdown
What it's made of and why it matters
Mist of Wonders is an aqueous leave-in spray designed for curl definition and moisture retention. The formulation relies on humectants (likely glycerin or similar), conditioning polymers, and emollients rather than film-forming resins or heavy silicones. Leave-in sprays of this type have minimal thermal stress because they are not heated during application, reducing risks associated with volatile compound release or polymer degradation.
The brand's record and disclosure
DevaCurl has not disclosed PFAS testing or water-resistance treatment status for this product, which is typical industry silence rather than a red flag. The brand markets to curl-focused consumers and does not appear on major environmental watchdog lists for cosmetic safety violations. No recalls or widespread adverse event reports are on record for Mist of Wonders specifically.
How it compares in its category
Leave-in curl sprays are generally lower-risk than aerosol styling sprays because they avoid propellant inhalation hazards and pressurized heating. Mist of Wonders sits in the mid-market segment; it is formulated without heavy perfumes typical of mass-market alternatives but does not carry third-party certifications (Clean Beauty, EWG, etc.) that some premium competitors do. For a leave-in application with no heat contact, this product profile is safer than thermal sprays or aerosol formulations.
If you buy it
Apply to damp or dry curls without heat; the product is not designed for blow-dry use and requires no special maintenance. Patch test on a small section if you have sensitive scalp or known fragrance sensitivities, as the ingredient list does not disclose fragrance components publicly. Store in a cool, dark place to preserve humectant integrity; do not apply to skin near the eyes. Replace after 12 months or if separation or odor changes occur.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Fragrance allergens and undisclosed fragrance components
DevaCurl products typically contain fragrance blends that are not individually itemized on the label due to trade secret exemptions. Individuals with fragrance sensitivity or scalp dermatitis may experience irritation; no specific allergic reactions are documented on record for this product.
Formaldehyde-releasing preservatives
No public documentation indicates DevaCurl uses formaldehyde-releasing preservatives (e.g., DMDM hydantoin) in this formula. Water-based leave-in sprays typically use gentler preservative systems, but the full ingredient list is not publicly disclosed.
Talc contamination
Mist of Wonders is a liquid spray, not a powder product, so talc exposure risk is not applicable. This hazard class does not apply to leave-in spray formulations.
Heavy metals in conditioning agents or colorants
The product is a clear or translucent spray without pigments or dyes, and typical hair conditioners do not accumulate heavy metals in measurable amounts during leave-in use. No testing or recalls have flagged metal contamination in DevaCurl products.
Scalp irritation from alcohol content
Leave-in sprays may contain alcohol as a humectant or preservative booster; if present at high levels, this can cause dryness or irritation on sensitive scalps. DevaCurl does not publicly disclose alcohol concentration, so individual tolerance varies.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
