Detailed answer

A balanced diet rich in vitamins, minerals, and protein is essential for maintaining healthy hair. Nutrients like biotin, vitamin A, vitamin C, iron, and omega-3 fatty acids promote hair growth and prevent hair loss. Conversely, a poor diet lacking these nutrients can lead to weak, brittle hair, hair loss, and slower hair growth. Additionally, dehydration and excessive intake of processed foods, refined sugars, and unhealthy fats can negatively impact hair health. Therefore, adopting a nutritious diet with a variety of fruits, vegetables, lean proteins, whole grains, and healthy fats is crucial for maintaining optimal hair health.
