Telogen phase of hair cycle lasts for
**Core Concept**
The hair growth cycle consists of three phases: anagen, catagen, and telogen. The **telogen phase** is the resting phase of the hair cycle, during which the hair follicle is dormant. This phase is crucial for understanding hair growth patterns and disorders.
**Why the Correct Answer is Right**
The telogen phase typically lasts for approximately 3 months. During this phase, the hair follicle is in a resting state, and the hair is released from the follicle, leading to shedding. The **telogen effluvium** occurs when there is a significant increase in the number of hair follicles entering the telogen phase, resulting in excessive hair shedding.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the anagen phase, not the telogen phase, lasts for several years.
**Option B:** This option is incorrect because 1 month is too short for the telogen phase.
**Option D:** This option is incorrect because 6 months is too long for the typical telogen phase duration.
**Clinical Pearl / High-Yield Fact**
The telogen phase is an essential aspect of the hair cycle, and understanding its duration is crucial for diagnosing hair-related disorders. A key point to remember is that the telogen phase lasts for about 3 months, and any significant deviation from this duration may indicate an underlying condition.
**Correct Answer:** C. 3 months.
