Brittle nails are treated the same way they are prevented, following the guidelines for bathing and using moisturizers. Several vitamins and minerals have been proposed for the treatment of brittle nails, but none have been proven effective in human studies.
There are no side effects to treatment, unless an individual is allergic to moisturizers. Those individuals should choose unscented or hypoallergenic moisturizers.
Moisturizer should be applied to the skin and nails on a regular basis as needed. This will help prevent symptoms from returning.
Any new or worsening symptoms should be reported to the healthcare provider.
