Apply cuticle oil and hand cream daily to keep your nails and surrounding skin hydrated and prevent dryness. Protect your nails from water and harsh chemicals by wearing gloves when doing household chores like washing dishes or cleaning. Be mindful of the products you use on your hands, as some can be drying and damaging to your nails. Avoid using your nails as tools to open things or pick at things, as this can cause breakage and damage. Picking or biting your nails or surrounding skin can weaken them and potentially lead to infection. If you need to trim or shape your nails, use a fine-grit file and file in one direction to avoid splitting. If you have acrylics or gels, it's best to have them removed by a professional to avoid damaging your natural nails.
