What are the main characteristics of fine hair?

Fine hair is characterized primarily by its thinner structure, which makes it more susceptible to damage compared to thicker hair types. This fragility can be attributed to the smaller diameter of each hair strand, making them more vulnerable to breakage from styling tools, environmental factors, and chemical treatments. Additionally, fine hair typically lacks volume, which can make it appear limp or flat, necessitating different styling techniques and products to enhance body and fullness.

The correct understanding of fine hair also delineates it from thicker, coarser types that possess more strength and volume, as well as higher resilience to damage. The attributes of shine and resistances noted in the other options do not accurately reflect the qualities of fine hair; instead, they are more commonly associated with different hair types or conditions.
