This is question we are asked daily and that's why we figured it would be vital to address it so everyone is clear on it.
So what do you do if your client is pregnant, breastfeeding of undergoing IVF? Is it safe to use henna on them?
Every colorant, including henna, has small traces of PPD in it. Therefore, we don’t advise you to use it if pregnant--however, at the end of the day it is your own risk. If your client is pregnant, breastfeeding or undergoing IVF, they must be made aware of the potential risks associated with tinting. This being, there is a minimal chance that the dye could sink into the skin and come into contact with the fetus.
We always advise beauticians to have their clients speak to their doctor or pediatrician before getting any henna or colouring treatments. Unless you have specific allergies to henna-based products, using henna typically causes no harm. But we always say safety first, and just like women have the choice to dye their hair or not while being pregnant--this is at their own risk as well.
Side note that is very important for both non-pregnant and especially pregnant clients: If your client is allergic to dye, tint, henna, PPD, or any form of colorant--do not proceed with the treatment. If your client has any type of eczema, psoriasis, dermatitis, rash, stye, etc. do not proceed with treatment. This is why patch tests on the arm are MANDATORY prior to accepting new clients.
We hope that this is somewhat helpful! Happy tinting!
