Do eyebrows stop growing at a certain length, or do they continue to grow indefinitely?

Eyebrows, like all hair on our body, have a growth cycle that includes a period of active growth, a transition phase, and a resting phase before falling out and regenerating. The length of the active growth phase for eyebrows is shorter compared to other hair on our body, which is why they typically have a shorter maximum length. While eyebrows do not continue to grow indefinitely, they may appear longer if they are not regularly trimmed or if the growth cycle is disrupted.
