Why does the hair on arms and legs get to a certain length and stop growing?
The hair on our arms and legs goes through a growth cycle that consists of three phases: the anagen phase, the catagen phase, and the telogen phase. The anagen phase is the active growth phase, during which the hair follicle produces a new hair shaft. The catagen phase is a transitional phase, during which the hair follicle shrinks and the hair shaft is pushed out of the skin. The telogen phase is the resting phase, during which the hair follicle is dormant and the hair shaft is shed.
The length of the hair on our arms and legs is determined by the length of the anagen phase. The anagen phase for hair on the arms and legs is typically 2-6 weeks. After the anagen phase is complete, the hair follicle enters the catagen phase, which lasts for about 2 weeks. During the catagen phase, the hair follicle shrinks and the hair shaft is pushed out of the skin. The telogen phase lasts for about 3-4 months, during which time the hair follicle is dormant and the hair shaft is shed.
Once the telogen phase is complete, the hair follicle re-enters the anagen phase and the cycle begins again. The length of the anagen phase determines the length of the hair on our arms and legs. People with longer anagen phases will have longer hair on their arms and legs.
