Pregnancy Safe Shampoo & Conditioner

Hey fellow mummies-to-be! I’m currently 6w pregnant and having a hard time trying to find pregnancy safe shampoos & conditioners that won’t leave my hair frizzy. Any recommendations? I’m currently using Tsubaki - understand that the ingredients are not exactly pregnancy safe. I’m intending to continue using this shampoo & conditioner until I manage to find a pregnancy safe one - not sure if there may be any issue with this? Thanks in advance!
