So I've been reading here about Terminal Length, and that after a certain period of time your hair enters telophase and stops growing.

But, your hair eventually comes out of telophase and begins growing again right? Or not? What triggers telophase? The weight of your hair on the follicle, or just some mysterious time clock hidden in the genes? Is it preset like leg hair to just grow a certain amount and be done?

How long will hair sit in telophase and have no growth? Lets say that a person's hair is on an eight year cycle- meaning it grows for eight years and then hits telophase- does that mean it grows for eight years and then takes an eight year break?

I'm confused.
