Nail salons, hair salons, and beauty service facilities represent occupational and customer environments where PFAS exposure from multiple sources — products, dust, and water — may be elevated compared to typical indoor settings. Workers who spend eight or more hours daily in these environments face cumulative exposures that deserve attention, and the water used in beauty services is one component of that exposure picture.
PFAS in Nail Products
The nail care industry has historically been a significant user of fluorinated compounds. PFAS in nail products serve several functions: providing chip resistance, improving adhesion, creating shine, and imparting water resistance. Common PFAS-related ingredients found in nail products include fluorinated monomers in gel formulations and PTFE (polytetrafluoroethylene) in some nail polishes marketed for durability.
A study by the Campaign for Safe Cosmetics found fluorinated compounds in multiple nail polish formulations, often without disclosure on product labels. The nail salon occupational setting — where workers are exposed to products throughout the workday in enclosed spaces — amplifies personal care product PFAS exposure far beyond what typical consumers experience from occasional home use.
Water in Nail and Beauty Services
Water is used extensively in nail and beauty services: manicure soaking baths, pedicure foot spas, hair washing stations, and facial steaming equipment all involve prolonged skin contact with water. In areas with PFAS-contaminated tap water, this occupational water exposure creates a dermal absorption pathway that adds to workers’ total PFAS exposure.
Pedicure foot spas deserve particular attention: clients and workers have extended, warm-water foot soaks — warm water may increase dermal absorption rates compared to cold water contact. For workers performing multiple pedicures daily, cumulative water contact time is substantial.
Hair washing stations involve scalp contact with potentially PFAS-contaminated water, and shampoo and conditioning products add their own potential PFAS exposure through the scalp — a skin surface with relatively higher permeability than most body skin.
Occupational Health Implications
Nail salon workers — disproportionately Vietnamese American women in the United States — already face recognized occupational health challenges from volatile organic compounds in nail products. Adding PFAS to this occupational exposure profile increases concern. Several worker health organizations, including the California Healthy Nail Salon Collaborative, have begun including PFAS awareness in their worker health programs.
Protective measures for salon workers include:
- Installing point-of-use filters on water used for soaking baths and hair services, particularly in PFAS-contaminated areas
- Transitioning to verified PFAS-free nail and hair products
- Improving ventilation to reduce inhalation of product vapors (which may include fluorinated compounds)
- Worker health monitoring in communities with documented PFAS water contamination
Customer Exposure Considerations
For customers, exposure during individual beauty service appointments is significantly lower than for workers due to duration. However, for frequent salon visitors — those receiving weekly manicures, regular pedicures, or frequent hair services — the cumulative dermal water exposure becomes more significant, particularly in PFAS-affected areas.
Practical Recommendations for Salon Owners
Salon owners in areas with known or suspected PFAS water contamination can take practical steps to reduce client and worker exposure:
- Test the salon’s water supply for PFAS through a certified laboratory
- Install certified filtration (NSF/ANSI 53 or 58) at water outlets used for soaking services
- Review chemical product suppliers and request PFAS disclosure
- Market PFAS-aware practices as a health and wellness differentiator — increasingly relevant to health-conscious clients
As PFAS regulations expand from industrial settings to consumer products and occupational environments, beauty service facilities will face increasing pressure to address their role in the broader PFAS exposure ecosystem.
