Is a keratin treatment safe during pregnancy?
Most OB/GYNs recommend skipping formaldehyde-based keratin treatments during pregnancy and breastfeeding due to fume exposure. Formaldehyde-free smoothing systems are a safer alternative.
Traditional keratin treatments can release formaldehyde when heated, which OSHA classifies as a known carcinogen at occupational exposure levels. Pregnant clients and stylists should avoid it.
Safer alternatives during pregnancy
- Formaldehyde-free smoothing (Cezanne, GK Hair pH+, some Inoar systems)
- Bond-repair treatments (Olaplex, K18)
- Glosses and deep-conditioning masks
Always tell your stylist you're pregnant so they can recommend the safest option and ventilate the workspace.
