The phases of the hair growth cycle are correctly identified as anagen, catagen, and telogen.

Anagen is the active growth phase of hair follicles, during which the hair is continuously produced and is around 85-90% of hair at any given time. This phase can last for several years, depending on various factors such as genetics and health.

Catagen is the transitional phase that follows anagen, during which the hair stops growing and prepares to enter the next stage. This phase is relatively short, lasting only a few weeks, and marks the end of the active growth phase.

Telogen is the resting phase where the hair is completely formed but not actively growing. It typically lasts for several months before the hair eventually sheds and a new anagen phase begins for a new hair growth cycle.

Understanding these phases is essential for professionals in the cosmetology field, as it can influence various treatments, hair care, and expectations regarding hair growth for clients.
