A trim will make eyelashes grow longer. We all heard since we were kids that trimming your hair makes it grow faster. Well, that's more of a misunderstanding than a myth. Technically, trimming hair doesn't speed up the growth process. It allows hair to grow healthier by removing split ends that cause damage. Your hair may look longer, but that's only because it's healthier. Unless your eyelashes are over six inches long, you don't have to worry about split ends. Trimming does nothing for eyelash growth.
