Congrats on the pregnancy! Honestly, I'd check with your doctor or gynae pasal eyelash perming during breastfeeding sebab chemicals involved boleh jadi concern, a few of my mum friends played it safe and waited til after bf period habis, tapi ada juga yang proceed je. Better safe than sorry, especially since we're passing things through breastmilk kan, so best to get professional advice from your doctor about the specific products they use at the salon.
