What term describes the growth phase of hair?

1. Telogen

2. Catagen

3. Anagen

4. Exogen

The correct answer is: Anagen

The growth phase of hair is referred to as the anagen phase. During this phase, the hair follicles are actively producing hair, and it can last for several years, with the length of time varying depending on individual genetics and health. In this phase, the hair actively grows and is anchored firmly in the follicle, allowing for the maximum length to be achieved. Each hair strand may spend differing lengths of time in the anagen phase, which is why some individuals may have longer hair than others. Additionally, the anagen phase is crucial because it determines the overall growth potential of the hair, and a healthy anagen phase contributes to thicker, fuller hair. The other terms relate to different stages of the hair growth cycle: telogen refers to the resting phase, catagen is the transitional phase after growth, and exogen is the phase associated with hair shedding. Understanding the anagen phase is key in hair care and treatments, as it provides insight into how to promote healthy hair growth.
