One way to prevent your hair from breaking and falling out is to keep it moisturized. You can do this using natural or synthetic products, depending on your hair type. For dry hair, you can try using a moisturizing shampoo or conditioner. You can also apply a humidifier to your home to add moisture to the air. If you have oily hair, you can use oil-free shampoos and conditioners that are designed for fine hair. If you have curly hair, you can apply conditioning treatments regularly to keep its individual cells hydrated.
