In which stage does hair grow in the hair growth cycle?

The hair growth cycle consists of several stages, and the anagen phase is specifically known as the growth stage. During this stage, the cells in the hair bulb divide rapidly, leading to the elongation of the hair strand. Typically, the anagen phase lasts for several years, and it's the period when the hair is actively growing and is at its thickest and healthiest.

In contrast, the telogen stage is the resting phase in which hair growth has stopped, and the hair is eventually shed. The catagen stage is a transitional phase where hair growth slows down and detaches from the follicle, while the exogen phase involves the shedding of hair that has completed its cycle. Understanding these stages is crucial for anyone studying cosmetology, as it can influence hair care routines and treatments.
