Ok Ladies... Fingernail Help!

I wore acrylics for 25 yrs, felt naked without them. In '09 when DH retired we left on our first extended trip. I went to nail places all over the west, some good, some not so good. In Washington state when I was going to have to wait several hrs to have fills done and pay $60, I decided to soak them off. After struggling with them for 6 months, they finally began to look healthy. My nails, like yours, are so thin that they peel and break easily. Someone told me about 5000 mg. Biotin, I also take calcium, and ever since I have taken these supplements I been able to have decent looking nails. It took some time, maybe 6 mo. to see progress. I do notice that they do much better whe we are on the road, probably because there is less housework and fewer dishes, even though I have a dishwasher at home. I still rinse everything. The other thing I do is file my nails a good bit, to erase any little nicks I might get. I also use buffing cream and a buffer.
