Long and full eyelashes make eyes look bigger and more defined. The presence of “lush” eyelashes gives an idea of young fertility, in a completely scientific, not conscious way. As people get older, hair and eyelashes fall out, brows thinning, skin loses elasticity. Long and full eyelashes, just like long, thick, shiny hair, are signs of beauty and youth. Also, the eyelashes compliment and draw attention to the windows of the soul as well as portraying virility. It’s all part of the weird scientific way we “mate.”
Just like first advise for anyone who wants to grow long hair is not abuse it, so goes about eyelashes.
Eyelashes are hairs, and use protein to build new cells.
