Nothing is working for my weak nails

Hi,



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?
Please help.

I didn't find the right solution from the Internet.
