Human hair varies widely and should be classified by curl type rather than race.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research The Effect of Relative Humidity on the Spreading of Ethanol on Human Hair Fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.
research The Hair Cycle on the Human Thigh and Upper Arm
Men's thigh hair grows longer and has a longer growth cycle than women's, but arm hair growth is similar between genders.
