Why do you have to wait for a goatee to grow back?

You have to wait for a goatee to grow back because hair grows at a relatively slow pace, typically only about half an inch per month. Additionally, shaving or trimming the goatee too frequently can cause damage to the hair follicles, leading to slower or patchy regrowth. It is important to allow the hair to grow back naturally and give it time to reach its full length before shaping or styling it again.

A goatee does not have to wait to grow back. Hair grows continuously and there is no need to wait for hair to grow back.
