Cute Young Blonde Girl Reveals Naked On The White Fur Carpet In The Grey Studio

Nature of fur
Fur usually consists of two main layers:
• Ground hair or underfur or down hair — the bottom layer consisting of wool hairs which tend to be shorter, flattened, curly, and denser than the top layer. Its principal function is thermal insulation and thus thermoregulation.
• Guard hair — the top layer consisting of longer, often coarser, straight shafts of hair that stick out through the underfur. This is usually the visible layer for most mammals and contains most of the pigmentation. It protects the underfur from outside factors, such as rain, and is thus often water-repellent.
