What happens to the hair bulbs during the catagen phase?

1. They grow longer

2. They become thicker

3. They disappear

4. They change color

The correct answer is: They disappear

During the catagen phase, the hair bulbs undergo significant changes as this stage marks the transition from active growth to a resting period in the hair growth cycle. Specifically, the hair bulb shrinks and begins to detach from the hair follicle. This process signifies the end of the anagen phase, where hair growth occurs, and initiates the transition into the telogen phase, which is a resting phase. As the hair matrix cells in the bulb cease to divide, the hair stops growing, and eventually, the bulb may be reabsorbed by the body, which is why it is described as disappearing. This understanding of the catagen phase is crucial for barbers to know as it can help them provide better advice and services related to hair care and client expectations regarding hair growth and maintenance.
