The concern about hair dye and pregnancy
One of the main concerns about hair dye during pregnancy is that the chemicals in hair dye could be harmful to the developing foetus. Some studies have suggested that hair dye chemicals may be absorbed through the skin and into the bloodstream. This absorption may be increased during pregnancy due to changes in the skin and blood vessels. There is also a concern that inhaling fumes from hair dye could be harmful to the developing foetus.
What do the experts say?
The NHS says:
"The chemicals in permanent and semi-permanent hair dyes are not highly toxic. Most research, although limited, shows it's safe to colour your hair while pregnant.
Some studies have found that very high doses of the chemicals in hair dyes may cause harm. However, these doses are massive compared with the very low amount of chemicals you may be exposed to when colouring your hair
You may decide to wait to dye your hair until after the first 12 weeks of pregnancy, when the risk of chemical substances harming the baby is much lower. If you're colouring your hair yourself, you can reduce the risk further by making sure you:
- wear gloves
- leave the dye on for the minimum time
- work in a well-ventilated room
- rinse your scalp once the dye is applied
Highlighting your hair, by putting the dye only on to strands of hair, also reduces any risk. The chemicals used are only absorbed by your hair, and not by your scalp or bloodstream.
Semi-permanent pure vegetable dyes, such as henna, are a safe alternative.
Do remember that pregnancy can affect your hair's normal condition. For example, your hair may:
- react differently to colouring or perming than it usually does
- become more or less absorbent, frizzy or unpredictable
It's always a good idea to do a strand test first using the hair dye or treatment you intend to use. Speak to your hairdresser for advice.
Some hair dyes to avoid during pregnancyWhile it's generally safe to dye your hair during pregnancy, there are some types of hair dye that you should avoid. These include:
1. Bleaching agents: Bleaching agents contain high levels of ammonia, which can be absorbed through the skin and into the bloodstream. This can be harmful to the developing foetus.
2. Henna: Henna hair dye is a natural alternative to chemical hair dyes, but it's not recommended during pregnancy. This is because it can interfere with some prenatal tests and make it difficult to detect foetal distress.
3. Semi-permanent hair dye: Semi-permanent hair dye contains fewer chemicals than permanent hair dye, but it still contains some. It's best to avoid it during pregnancy if possible.
Conclusion
In conclusion, it's generally safe to dye your hair during pregnancy, but you should take some precautions to reduce the risk of harm to the developing foetus. If you're concerned about using hair dye during pregnancy, speak to your healthcare provider for advice. They can provide you with more information and help you make an informed decision about whether or not to dye your hair during pregnancy.
