About 13and a half weeks to grow back to normal.About 13and a half weeks to grow back to normal.I was told it could be from a week to 6 months for all your eyelashes to grow back to normal.
Eyelashes take about seven to eight weeks to grow back. Castor oil or olive oil can usually help to grow back if the eyelashes are pulled out so don't worry if they fall out, they will grow back!!!
