How Body Hair Knows When to Stop Growing: Exploring the Hair Growth Cycle

Discover how body hair knows when to stop growing and learn about the hair growth cycle's phases.

47 views

Body hair knows to stop growing due to the hair growth cycle, which involves three phases: anagen (growth), catagen (transitional), and telogen (resting). Each hair follicle is programmed to grow hair for a specific duration during the anagen phase, after which it stops growing and eventually falls out during the telogen phase. This cycle is genetically determined and varies for different body parts, ensuring that body hair remains at a manageable length.
