What are effective treatments for split nails?

To treat split nails, hydrate them by adding creams, lotions and oils such as shea butter and jojoba oil. Also, avoid clipping and filing nails that are dry by moistening them and towel drying before using clippers or a file to prevent additional breakage, says Dr. Cynthia Bailey, dermatologist and skin care expert.

Protecting the fingernails with gloves before they come in contact with any harsh chemicals or while doing work that may cause drying and breakage is also recommended by Dr. Bailey. To repair a split nail, apply nail glue to the tear, let it dry and flatten and smooth it with a buffing tool, suggests Black Cat Nails.
