For those women who dye their hair, regrowth can be dreaded. There has always been the myth that dyeing your hair can harm your baby. Fortunately, this one is not true. The chemicals in both permanent and semi-permanent hair dye aren’t readily absorbed by intact skin and as a result, are unlikely to cause any harm to your baby. Research in this area is limited, however, colouring your hair three or four times during your pregnancy is safe.
If you are a little worried about any absorption then I do recommend waiting until 12 weeks to dye your hair. This prevents your baby from being exposed to chemicals whilst their vital organs are forming.
You can decrease absorption by minimising or avoiding any scalp exposure to chemicals; so highlights and balayage might prove an alternative. Using semi-permanent vegetable dye, such as henna is another alternative.
If you’re colouring your hair yourself, use standard precautions by:
- wearing gloves
- ensuring the room is well-ventilated
- leaving the dye in for the minimum amount of time required and
- thoroughly rinsing your hair at the end of the treatment.
If your skin is broken it can lead to increased blood absorption. It is best to avoid colouring your hair if your scalp has any scabs, broken areas, chemical burns or abscesses.
If you’re a hairdresser there is no need to worry. There is no evidence that working with hair dyes can harm your baby or cause a miscarriage. Just ensure you wear gloves and work in a well- ventilated salon.
