4. Spider Eyelashes. Unless it’s Halloween, do not keep your fake lashes long after they’ve crinkled or curled in unnatural ways. Sure, we know that you were promised the lashes would last a month, but if your mirror says otherwise, please remove them. Also, waterproof mascara may make natural lashes dry and that can make them thin and brittle. Ask your makeup artist for gentle mascara that will amplify your lashes without drying them out.
