Ive used Gena healthy hoof nail cream and its great!

eating healthy, handcream and hair skin and nail vitamins..also putting vitamin E on your nails may help…

Maybe salons have repair kits or can provide advice?

A local chemist should be able to advise about products for repairing nails.
Previously we purchased a little nail repair kit which was quite affordable and worked well.

I’ve heard nail strengtheners are good. I usually just try buffing them but they still seem to hurt and look quite bad. In time they go back to normal though. Sucks how acrylics look good for about a week then screw your nails for at least a month.
