In brief: Hair growth
Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen phases.
Each phase has specific characteristics that determine the length of the hair. All three phases occur simultaneously; one strand of hair may be in the anagen phase, while another is in the telogen phase.

Agree! This is important when we use 'Anagen promoting agents' like minoxidil, finasteride, laser therapy or PRP. These treatments for hair regrowth can cause a temporary shed when triggering the Anagen Phase in hair follicles before the resulting hair growth is measurable/noticeable... which take many months.
