it will take about 3 months for your eyelashes to grow back in completely - that is a normal growth cycle.
there are some products on the market that claim to promote eyelash regrowth - Talike Eyelash Lipocils ($38 at Sephora), and Global Goddess Coconut Amla Lash & Brow Conditioner ($21 at Sephora).
other people recommend applying warm vitamin E oil to the area. other than drugs recommended for the purpose, i suspect you'll have to wait for the regrowth cycle. once you have something for them to grab on to, try individual lashes if you feel you really need them.
(speedy recovery, liz!)
