men generally also have coarser hair than females, but the woman's hair is more dense and
the man's hair grows faster than the woman's hair

human hair grows quicker in warm weather

Young versus elderly:
Elderly people have slower hair growth and diminished hair density

Humans versus animals:
human body hair is barely visible as it is thinner, shorter, and more translucent than the hair of other mammals

Light versus dark:
all natural hair colors are the result of two types of hair pigments: dark (eumelanin) and light (phaeomelanin).
Eumelanin is the dominant pigment in dark-blond, brown, and black hair,while pheomelanin is dominant in red hair. Blond hair is the result of having little pigmentation in the hair strand.
