If a goatee fully grows back in two to six months, does that mean that the anagen phase, the telogen phase, and the exogen phase are involved in how a goatee fully grows back?

Yes, the growth of a goatee involves all three phases of the hair growth cycle: anagen, telogen, and exogen.

During the anagen phase, the hair follicles are actively growing and producing new hair. This is the phase where the goatee is actively growing and getting longer.

The telogen phase is a resting phase where the hair follicles are not actively growing. This phase typically lasts for a few weeks to a few months before the hair eventually falls out.

The exogen phase is when the old hair sheds and new hair begins to grow in its place. This phase is essential for the renewal and regrowth of the goatee.

So, the fact that a goatee fully grows back in two to six months indicates that all three phases of the hair growth cycle are involved in the process.
