0 views

Arm hair, like all human hair, goes through a growth cycle that includes phases of growth, rest, and shedding. However, unlike the hair on your head, arm hair reaches a certain length and then stops due to a shorter active growth phase. This length is genetically determined and varies from person to person. Therefore, while arm hair does stop growing at a certain point, it will continue to go through its natural cycle of growth and shedding.
