Stages of hair growth
The hair growth cycle consists of four stages: anagen (growth), catagen (transition), telogen (resting), and exogen (shedding). Each hair follicle on the body undergoes this cycle independently, meaning that not all hairs are in the same phase at the same time. Here's a more detailed breakdown of each stage: Anagen (Growth Phase): This is the active growth phase where the hair follicle produces new hair. It can last for several years, with head hair typically growing 0.3 to 0.5 cm per month. Catagen (Transition Phase): This is a short transition period where the hair follicle begins to shrink and the hair stops growing. Telogen (Resting Phase): During this phase, the hair follicle is dormant, and the old hair strand remains attached. After a few months, the hair naturally sheds. Exogen (Shedding Phase): This is the shedding phase where the old hair is released, and the follicle prepares for a new anagen phase.
