Repeated chemical exposure and harsh environments can leave nails brittle and splitting. Fungal infection and hypothyroidism may contribute, especially if weight gain, fatigue, or low mood accompany changes. Breakage can also reflect low biotin, protein, or iron. Excess washing, detergents, and cold dry air worsen fragility. Protective gloves, routine moisturizers, balanced nutrition, nail strengtheners, and moderate length help reduce further splits.
