What is the dormant phase of hair growth termed when cell multiplication halts?

The dormant phase of hair growth, when cell multiplication halts, is correctly referred to as the telogen phase. During this phase, hair follicles are in a resting state, and no new growth occurs. The telogen phase typically follows the anagen phase, which is the active growth phase, and precedes the shedding of hair. Understanding the lifecycle of hair is crucial for practices such as waxing, as it helps in determining the appropriate timing for hair removal treatments.

In contrast, the anagen phase is when hair is actively growing and the follicles are engaged in cellular division. This is the phase where waxing would be most effective for hair removal. The term "catogen" is not a recognized phase in the hair growth cycle; instead, it may be a misinterpretation of the catagen phase, which is a transitional phase where hair growth slows, but this period does not represent a complete halt in cell multiplication. Lastly, "keratogenous" is not a relevant term in the context of hair growth phases, as it refers to the formation of keratin, rather than a specific phase of hair growth. Thus, the telogen phase is accurately adopted as the term for the dormant phase in the cycle of hair growth.
