Question

Quizplus · Accepted Answer

The length of uncut hair is primarily determined by the growth rate of hair and the duration of the hair growth cycle. Variations in hair growth rate and the duration of the growth cycle can result in differences in hair length among individuals. The thickness of the individual hairs and quality of conditioning treatments may also play a role in hair appearance but do not affect the length of the hair itself.
