Just like hair dye, the chemicals used in nail treatments are in low doses and not readily absorbed by your skin.
As with any chemical the greatest concern is long term exposure to a chemical or a once off very high dose of a chemical. This could result in high blood levels of the chemical and usually causes continual chronic headaches. If such levels are reached then it could result in miscarriage – however the research is very limited and conflicting.

So follow the same simple steps as for hair colouring to minimising absorption and therefore the risk to your baby. If you have any cuts to the nail bed its best to avoid any nail treatments.

The fumes given off from the acrylic products might cause you to feel nauseated and sick. This can happen if you’re pregnant or not. Some women may get an allergy to the acrylic nail or develop a fungal or bacterial infection due to changes in the immune system whilst pregnant. In this case avoiding future treatments is best.

For women who are pregnant and working in nail salons with acrylic nail products; ensure the area is well ventilated and protect your skin from exposure to chemicals by wearing gloves. Have a discussion with your employer to see if you can limit the time you spend around these chemicals and ensure you get some fresh air throughout the day.
Fortunately in pregnancy your nails are usually healthier and stronger, so for some women avoiding exposure to treatments may not be such a bad thing at all.

During pregnancy, 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 in pregnancy is safe.

If you are a little worried about any absorption then and waiting until 12 weeks to dye your hair prevents baby being exposed to chemicals whilst his/her vital organs are forming. You can decrease absorption by minimising or avoiding any scalp exposure to chemicals; so highlights and balyage might prove an alternative. Using semi-permanent vegetable dye, such as henna is another alternative, otherwise If you’re concerned, consider using a colouring technique that doesn’t cover all of the hair. For example, babylights, ombré or balayage will allow you to freshen up your look but the hair dye is not in direct contact with your scalp.

If you’re colouring your hair yourself, use standard precautions by:

  • wearing gloves;
  • ensure the room is well-ventilated;
  • leaving the dye in for the minimum amount of time required and;
  • thoroughly rinse your hair at the end of the treatment.

If your skin is broken it can lead to increased blood absorption; so it’s best to avoid colouring your hair if your scalp has any 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.

The active ingredient in fake tan is dihydroxyacetone (DHA). It reacts with the cells in the outer most layer of skin, producing a brown pigment called melanoidin. Fortunately it doesn’t penetrate the skin much further, so isn’t absorbed by the blood stream. It’s safe to use in creams and lotions.

It’s safest to avoid spray tans given that you can inhale DHA which might make it more easily absorbed.

Fake tan can cause an allergic skin reaction in pregnancy due to the changes in a woman’s immunity. So prior to using any lotion or cream to the whole body, do a test on a small patch of skin that is well hidden.

You can continue with your waxing regime. The only issue is that you might find your skin becomes more sensitive especially in the pubic area. This is due to changes to your hormones and the blood flow to that area in particular. Waxing might result in some bruising.

The use of a depilatory cream might result in an allergic reaction that wasn’t present when you weren’t pregnant. If you have an allergy, don’t use it anymore and try a small test dose 2 months after pregnancy.

Botox or botulinum toxin is used for cosmetic purposes as well as for headaches. Despite its use in women who might be pregnant there is limited research to show its effects on pregnancy or the fetus.

Botox is a large molecule show doesn’t cross the placenta. However whilst it might not cross over to baby it has been shown in animals that high levels of Botox resulted in miscarriage. It is for this reason that Botox should not be used during pregnancy. The same considerations should be made for dermal fillers such as Radiesse, Belotero, Restylane and Juvederm.

Limited data is available as to whether Botox and dermal fillers passes into breast milk. So that means no Botox or fillers until you have stopped breastfeeding.
