Can I dye my hair while pregnant?
Many providers say hair dye is generally considered low risk during pregnancy, since little dye is thought to pass into the body through the scalp. Ask your doctor or midwife before you dye, especially if you have concerns.
Key points
- Most guidance treats hair dye as low risk, but the research is limited.
- Protecting your scalp and skin and keeping the room ventilated may lower exposure.
- Your provider can help you weigh the choice based on your health and pregnancy history.
Why it matters
Hair dye contains chemicals that can be absorbed through the scalp and skin in small amounts. Researchers have studied hair dye in pregnancy, but the studies are limited, and many have not shown clear harm. Because of that uncertainty, many providers suggest talking it over first.
General pregnancy safety guidance from the CDC and NICHD recommends that you talk with your provider about any product or medicine you plan to use while pregnant.
What is generally considered OK vs. less certain
- Generally considered lower risk: Using dye at a salon with good ventilation, or using a dye that does not touch your scalp (such as highlights applied away from the roots).
- Less certain: Dyeing at home with strong fumes in a small room, using products with harsh ammonia or strong chemical smells, or frequent dyeing.
- No clear answer by trimester: Guidance does not show a clear difference between the first, second, and third trimesters. Some people choose to wait until after the first trimester, which is a personal choice to discuss with your provider.
Practical tips
- Follow the product’s directions and keep the dye off your scalp and skin when you can.
- Dye in a well-ventilated room, or ask a salon to use a ventilated area.
- Wear gloves and rinse well.
- Consider waiting a few days between dye sessions to limit how often you are exposed.
- Ask your provider about any gentler or plant-based options, and know that some “natural” products are not tested for pregnancy safety either.
If you already dyed your hair
If you dyed your hair before you knew you were pregnant, many providers say this is generally not a reason for alarm. Mention it at your next visit so your provider can answer your questions and track your health.
When to contact your provider
Contact your provider right away if you have a rash, itching, swelling of the face or lips, trouble breathing, or a severe headache after dyeing your hair. Those can be signs of an allergic reaction.
Questions people ask
Can I dye my hair while pregnant in the first trimester?
Many providers say hair dye is generally considered low risk in the first trimester, but the evidence is limited. Some people choose to wait until after the first trimester. Ask your provider what they recommend for you.
Can I dye my hair in the third trimester?
Guidance does not show a clear difference in risk between trimesters. Many providers consider dyeing low risk in the third trimester too, with good ventilation. Ask your provider if you have any concerns.
Is highlighting safer than full-color dye?
Highlights applied away from the scalp may reduce skin contact, which some people choose for this reason. Research is limited, so ask your provider for guidance on what fits your situation.
Can I use a semi-permanent or henna dye instead?
Products labeled natural or henna are not always tested for pregnancy safety. Check ingredients and ask your provider or pharmacist before using any of them.
