Not much short of using the prescription Latisse suggested by @Judi. Be warned that product can change your eye color permanently. If you are blue or green eyed I would not touch it with a ten foot pole. Actually, I would not use it no matter what, but that’s me. If your eyelashes are much thinner and falling out more often now compared to what they used to be, and you also have the hair on your head falling out significantly consider getting a thyroid test. Simple blood test, not expensive. If you have never had very think long lashes, then that’s what you have. Some mascaras are much much better than others to enhance them. MAC just came out with a new one, that I wish I knew the name of for you, but anyway it is the new one. And, layering Lancome Definicils with Hypnose will give you very full lashes. Definicils goes on first.
