I recently noticed a small bald area on my upper right outer corner eyelashes.. what would cause this? will it regrow? is there something i can do to condition the area? please help, this is very disturbing for me?

You need to see Dermatologist to find out cause of hair loss and what to do about it.

I assume you haven't been traumatizing your eyelashes and there has been no infection or thyroid disoreder. This may be alopecia aerata, an autoimmune disorder. In time this usually improves. A dermatologist can advise you & usually determine if the eyelashes will regrow. A cosmetologist can advise you how to improve the appearance.

Do you use artificial eyelashes? Removing these could cause some of your own eyelashes to be removed. A different brand of mascara or eye makeup? If no other eyelashes are affected, it seems more likely to be something like that. Avoid all eye makeup and see if they grow back. If you begin noticing loss of lashes elsewhere, see your doctor as there may be a more systemic reason for the loss.
