How do you stop spliting fingernails?

To stop splitting fingernails, keep them moisturized by applying hand cream and cuticle oil regularly. Avoid excessive exposure to water and harsh chemicals, and consider wearing gloves while doing household chores. Maintain a balanced diet rich in vitamins and minerals, particularly biotin, to promote nail strength. Lastly, trim your nails regularly and file them gently to prevent snagging and further damage.
