The speed at which eyelashes grow can vary from person to person, but it generally takes three months for eyelashes to grow back fully. Eyelashes grow in one-month to three-month cycles.
To prevent the further loss of eyelashes, recommendations include using gentle eye make-up removers and using eyelash curlers less frequently. Eating a balanced diet with plenty of protein is key as well. Stress can lead to hair loss, including eyebrows and eyelashes. Topical medication that stimulates the growth of eyelashes is also available, both over the counter and with a doctor's prescription. Additionally, many mascaras offer conditioners, such as vitamin E, which keeps eyelashes looking full and soft.
