Dr. Zakia Dimassi Pediatrics
The limited number of research studies indicates the chemicals found in both semi-permanent and permanent dyes are not highly toxic and are safe to use during pregnancy. Another reassuring fact is that only small amounts of hair dye may be absorbed by the skin with little that would reach the fetus. Such small amount is not considered harmful to the fetus. The same applies to breastfeeding.
If you are reluctant to use regular hair dyes during pregnancy, you may opt safer alternatives, such as having highlights which decreases any risk as the dye is only applied on strands of your hair and does not get in contact with the scalp. Another alternative is pure vegetable dyes including henna. If you are still not so sure, you may consult your obstetrician, as some physicians recommend waiting until after pregnancy to dye your hair, but in principle you're good to go since you're in the last 2 weeks of your pregnancy course.

Precautions to take include:
Make sure the treatment is done in a well-ventilated area.
Do not leave the chemicals on your hair any longer than indicated by the directions.
Rinse your scalp thoroughly with water after treatment.
Wear gloves when applying treatment.
Carefully follow the directions on the package.
Do a patch test for allergic reactions before completing the process.

You also need to to keep in mind is the fact that pregnancy, in itself, can change the hair’s texture and may also cause your hair to react differently to perming or coloring. If this is the case, you may want to wait until after pregnancy to treat your hair.
