Hair is a defining feature of personal style and identity, varying in texture, color, length, and type. It grows from follicles in the skin and consists mainly of keratin, a tough protein. Hair can be straight, wavy, curly, or coiled, influenced by genetics and environmental factors. Proper care—through cleansing, conditioning, and protection—helps maintain its health and vitality. Styling choices, such as cutting, coloring, or heat treatments, allow for creative expression but may also cause damage if not managed carefully. Hair plays a cultural and social role, often symbolizing beauty, status, or tradition across different societies. Whether natural or styled, hair remains an important aspect of self-presentation, evolving with trends and personal preferences while reflecting individuality.
