Is hair dye safe during pregnancy?
Most research suggests modern hair dye is low-risk during pregnancy, especially after the first trimester. Many providers prefer highlights or balayage so the dye doesn't touch the scalp.
There is limited evidence that the small amount of chemicals absorbed through the scalp during a normal coloring service is harmful in pregnancy. The American College of Obstetricians and Gynecologists (ACOG) considers occasional hair coloring to be a low-risk activity.
Lower-risk options
- Highlights, foils, or balayage — color doesn't touch the scalp
- Ammonia-free or plant-based color (henna, herbal)
- Wait until the second trimester if you can
Ventilation matters — color in a salon with good airflow, not a closed bathroom at home.
