Be careful of things you put close to your eye. The only FDA-approved product to grow lashes is Latisse, which requires a prescription. See your eye doctor for details. There are products that use Castor oil which is said to do a lot of things. Basically, it moisturizes the follicles. If you keep them clean, then those might work.
I wore false lashes for years (see profile pic), but removing them was pulling out lashes. Later, I had eye surgery and I noticed my right eye had fewer lashes than my left. Adding the Super B vitamin supplements (with Biotin) helps hair grow and my lashes are getting fuller. I see my eye doctor in September, so I plan to talk to her about prescribing Latisse and see if that helps.
