Fine hair refers to hair strands that are thinner in diameter compared to medium or coarse hair types. It often feels soft and silky, making it more prone to damage and breakage. People with fine hair may find it lacks volume and can appear flat, especially when weighed down by heavy products. This hair type can be influenced by genetics and can vary in texture, color, and overall health. Fine hair can be styled in various ways, but it often benefits from lightweight products and techniques that add volume without causing heaviness, such as using mousse or dry shampoo.
