There are many tans that manufacturers recommend not tanning pregnant women with. It’s not because the tan goes patchy or oddly streaky (which it often does with hormones) but because of the inhalation risk to the baby.
Whilst her op is tomorrow, I’d just be a bit wary because they are often because of an issue with babies health that requires it.
I don’t tan pregnant women, a) because the tan I use is not suitable during pregnancy b) because of my insurance and c) Because of my personal choice. A pregnant lady buying a beer and then drinking it is a bit different because it’s not like the bartender is pouring the beer down her throat, she is. Us spraying is like that to me. She can absolutely decide what she puts on her body and use a self tanner on her body, but we should not be putting stuff in her lungs during pregnancy unless we are doctors. At the end of the day it’s a chemical and pregnant ladies can’t even take anti-histamines, which is why allergies are so hard to treat during pregnancy. Anything she inhales goes straight to the baby.
But of course, my own business is different to yours and you need to make the decision for your client.
If you are comfortable with it, and she is happy with it, and she has a bit of paper from her doctor or signs something to say her doctor is ok with it, your insurer is ok with it, then go ahead; but not without that paper.
It might be better to say you are fully booked to save her getting stressed and part about it. A pregnant lady didn’t read the info i sent her the day before her tan and when I said that I don’t do it (I don’t do any treatments in first trimester as midwives recommend), she hit me and then was howling in my hallway for 30mins and screaming. Not the safest predicament i’ve been in.
