Why do eyebrows stop growing at a certain length?

How does hair on your arm know when to stop growing?
The growth of hair on your arms is regulated by hormone levels in your body. Hair follicles go through cycles of growth, rest, and shedding, and the length of the growth phase determines how long the hair will grow before it stops and falls out. Once a hair reaches a certain length or the growth cycle is complete, it will naturally stop growing and eventually be replaced by a new hair.
If some arm hair was burned or cut off what controls the regrowth so that it grows back to the same length as the rest of the hair on the arm?
The length of all of your body hair, including arm hair is controlled by the growing cycle. A hair strands growth cycle consist of: a growing period a resting period falling out and start of new growth period with a new hair strand. The length of the growing period is fixed for each type of hair (like arm hair). The hairs grow a certain amount every day during the growth period and then stop growing. When they stop growing they are all the same length since they have grown the same amount each day for the same number of days. Usually the hairs on your arm (or leg or head) are in a mixture of different periods; otherwise all the hair would fall out at the same time. This is why the hair on your legs looks thinner after you have shaved them; only the hairs in the growing period start growing right away.
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.

When does your pubic hair start growing?
It doesn't. Hair grows at different speeds, and has a finite 'lifespan'. Therefore, any given strand of hair can only grow to a maximum length before it is replaced by a new hair.Answer 2I know all hair gets eventually replaced, but it looks like it's a long process: before we shave a zone, for example most of hair is not growing, as it reached its max length, after we shaved it, almost all of it is growing back, so it seems like the hair can tell it has been cut :). The proportion reverts again once the hair reaches back to its genetically pre-determined length.
