No. Every follicle runs its own cycle: a long growing phase, a short transition, then a resting phase before the hair releases and the follicle starts again. Each follicle is on its own clock, out of step with its neighbours, which is why you shed a little every day instead of moulting in patches.

Your hair isn't growing continuously. Every follicle runs its own cycle. A long growing phase, a short transition, then a resting phase before it releases and starts again. And every follicle is on its own clock, out of step with its neighbors. That's why you shed a little every day instead of molting in patches like a dog.
This is why hair questions are answered in months. A follicle that is nudged onto a different path today will not show it on your head for a season, and it is why doctors who track hair properly measure at the start and measure again later, rather than judging by memory.
