What is the resting stage of hair growth called when there is no attached root sheath?

• A. Anagen stage
• B. Telogen stage
• C. Catagen stage
• D. Exogen stage

Answer: (B)

The resting stage of hair growth is known as the telogen stage. During this phase, hair growth halts, and the hair follicles remain inactive. In telogen, the hair is released from the follicle, and there is no root sheath attached to the hair strand. This is a natural part of the hair growth cycle, where the hair can be shed and eventually replaced by new growth as the cycle continues. In contrast, the anagen stage is characterized by active hair growth, and the roots are firmly anchored in the follicle with an active root sheath present. The catagen stage is a transitional phase where hair growth slows down, and the follicle begins to shrink, but hair still remains attached. The exogen stage refers to the process of hair actually falling out, which can occur at the end of the telogen phase but is not specifically the resting stage since it usually follows telogen. Thus, the telogen stage appropriately describes the period when the hair is at rest without an active root sheath.
