There are so many reasons why some people might have stronger lashes than others, but some include:
Genetics – some people have genetically longer, thicker and naturally curled lashes.
Hormones – puberty can affect lash growth and hair health.
Daily habits – rubbing your eyes excessively can cause your lashes to fall out. Using old or expired mascara or not removing makeup properly can also lead to inflammation and damage of the hair follicles.
Balanced diet – if your diet has plenty of zinc and vitamins A, B and E, this can help to support the growth and strength of your lashes.
