Rebonding hair during pregnancy I'm 24 weeks now.

Pls don't, I don't know what chemicals you are using for home DIY and if it is safer/less chemical than the salon's, but exposure to chemicals and fumes can cause birth defects and future health problems for the baby. This is even so when you are breastfeeding.

I rebonded my hair at 26 weeks, my gynae said it was fine

I'll try not to but read somewhere that it's ok
