2.Split or Cracked Nails
Daily exposure to chemicals, water, or dry environments can weaken nails, making them brittle and prone to splitting. Fungal infections and hypothyroidism are also common causes. If you experience fatigue, weight gain, or low mood, thyroid issues might be involved. Nutrient deficiencies—like lack of biotin, iron, or protein—can play a role too. Protect your hands with gloves, moisturize regularly, and maintain a balanced diet to keep nails strong.
