Like all hair on the human body, are made up of 10% water and 90% proteins such as keratin and melanin, the substance that give hair its color. Each eyelid typically has 200 individual lashes, while bottom eye lids have as many as 100.
Genetics, manipulation from styling, medical conditions, excessive rubbing/scrubbing can impact the health of your eye lashes. Be gentle on your eyes! Eyelashes are delicate and can be damaged or even lost from rubbing and tugging of everyday makeup and beauty practices.
