Cute Young Brunette Girl With Long Hair And Blue Eyes Shows Off On The Red Armchair

Human hair growth
Hair grows everywhere on the external body except for glabrous skin, such as that found on the soles of the hands, feet, and lips. It does not grow on mucus membranes either.
Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen phases. Each phase has specific characteristics that determine the length of the hair. All three phases occur simultaneously; one strand of hair may be in the anagen phase, while another is in the telogen phase.
