Judy, I never lost all my lashes at once. I noticed that they thinned out a lot..and one day I noticed that there were a couple long ones that just fell out, but I had a full lid of lashes behind it...they just had not yet grown in. So by the time the last ones fell out, I had gone a full cycle of lashes! I do not think conditioning them will help, it has to do with the growth process. It gets interrupted with chemo, so if they are going to fall out, I don't think you can stop them.
The others, like Bev, eill have great advice to help you get by. You may contact American Cancer Society to see about
their Look Good Feel Better class. It is free, and they offer tips on makeup and beauty issues during chemo.
Hang in there Judy!
