I totally get it, week 9 was rough for me too and everything smelled so strong suddenly. I switched to unscented baby shampoo and body wash from the supermarket (Pigeon and Cherub Baby are good options) because they're genuinely minimal, and honestly they worked better than "fragrance-free" labels which sometimes still have a faint smell. You might also want to look at sensitive skin ranges, though just tell the shop staff you need truly scentless rather than just mild because that makes a difference.
i feel you i couldn't stand all kind of smells. i couldn't find a replacement shampoo. but for body soap dr bronner unscented worked for me
