The hair growth stage known as the "resting phase" is:

1. Anagen

2. Catagen

3. Exogen

4. Telogen

The correct answer is: Anagen

The resting phase of hair growth is correctly identified as the telogen phase. During this phase, hair follicles are in a state of rest, where the hair does not grow but remains attached to the follicle. This phase can last for several weeks to months, depending on individual factors such as genetics, health, and environmental conditions. The anagen phase, often confused with telogen, is the active growth phase where hair cells divide rapidly, and the hair grows longer. The catagen phase is a transitional stage that follows anagen, during which hair growth slows and the hair follicle shrinks. Lastly, the exogen phase is part of the shedding process where old hairs fall out, making room for new hair to grow. Understanding these phases is crucial for professionals in cosmetology to provide appropriate treatments and aftercare to clients.
