I think the best thing you can do to achieve stronger nails is to use a buffer at home regularly (once every 4 days or so) and then paint a clear nail strengthening varnish over the top. I think a balanced diet, low in fats and with plenty of variation helps as well. I used to have weak nails and buffing them and using the clear polish really worked. Mine are now long and really strong, people always ask how I manage to grow them. Give it a go, I used an Avon nail varnish, but this was 15 years ago that I did that and they are still strong!
eat jello is what i always heard, u can get skin and nail vitamins and Avon sells some polish that helps.
you need calcium and protein such as milk, beans, meat and eggs.
