SAEDNEWS: Many women worry about the right time to dye their hair during pregnancy and whether it could harm the baby. During pregnancy, everything you do—such as coloring your hair, your diet, and daily activities—can have a direct impact on the fetus.
According to Saed News Family Health Service, hair dye comes into contact with your scalp and forehead, allowing chemicals to enter your body. Here’s what you should know about dyeing your hair during pregnancy.
Is Hair Dye Safe in the First Month?
Most doctors advise against coloring hair in the first month of pregnancy. Chemicals in hair dye can be absorbed through the scalp and enter the bloodstream. Animal studies suggest these chemicals may cause birth defects. Instead, consider stylish updos to enhance your hair without dye.
Hair Dye in the Second and Third Months
Doctors generally recommend avoiding hair dye from the first to the third month, as this is when the embryo’s cells develop and are highly sensitive. Exposure to chemicals during this time may harm your baby.

Hair Dye from the Fourth to Ninth Month
After the first trimester, your body gradually adapts, and tolerance to chemicals increases. However, skin sensitivity is heightened during pregnancy, and hair dye can still cause allergic reactions or other issues.
Safe Ways to Dye Hair During Pregnancy
If necessary, use pregnancy-safe dyes, such as temporary or ammonia-free options. Perform a patch test by applying a small amount to the back of your head, washing it off after 20 minutes, and waiting 72 hours. If no redness, itching, or bumps occur, you can dye your hair safely.
Dyeing Hair in the Last Month
As the baby develops, chemical risks decrease, but hair dye is never completely risk-free. Always consult your doctor before coloring your hair.
Key Takeaway
Avoid hair dye during the first three months of pregnancy. From months four to nine, temporary or ammonia-free dyes are safer, but caution is still advised to protect both your health and your baby’s development.
