I'm not sure why, but lately my nails have been bending, peeling and breaking like crazy! I take a Biotin supplement, and I've tried OPI Nail Strengthener for dry, brittle nails and Seche Plus Nail Strengthener and neither seem to help. I've read a ton of reviews and those two seemed to be the most popular. I paint my nails at least once a week and always use a base and top coat, and my nails look great until one of them virtually snaps in half a day or two later. I do the strengthener, a base coat, usually Julep polish, and then a top coat. Any suggestions ladies?
