I recently started using a lash-lengthening product, and it resulted in some of the lashes in the outer corner of one eye completely curling inward and touching my eyelid. So, I have 7-10 eyelashes that are curled in in just one spot, and it had been driving me crazy.
I searched the internet to find a product to straighten eyelashes... to many it sounds like the opposite of what you'd want, but apparently a lot of women have this problem! Anyway, someone mentioned a heated eyelash curler wand, so I immediately ran to my local Ulta and picked up this Japonesque product.
It's really great - very small (size of a mascara tube) and it heats up in about 15 seconds - but it does take some maneuvering to get the job done. For example, you have to hold your finger under your lashes as you use the wand on top in order to curl the lashes how you want. I work slowly so I make sure I'm heating all parts of the lash. If you want the curl to stay, you have to hold your lashes for a few seconds for it to "set." I THEN put on mascara (if you wait too long, I've found the lashes may go back to their original state). The directions say to use the curler AFTER you've applied mascara, but I haven't done that for fear it would melt some of the mascara and/or get mascara inside of the eyelash curler and gunk up the inside.
So, this definitely takes a little skill and a little more time than your typical non-heated "squeeze and go" eyelash curler, but if you're looking for a way to gain better control of some unruly lashes, I highly recommend this product.
