Michigan Barber Practice Exam

During the catagen phase, what happens to the hair?

1. It grows rapidly

2. The hair bulbs disappear

3. Hair turns grey

4. Hair follicles shrink

The correct answer is: The hair bulbs disappear

During the catagen phase, the hair follicle begins to detach itself from the hair bulb, which is the root of the hair. This results in the disappearance of the hair bulb. Option A is incorrect because the hair does not grow rapidly during the catagen phase, rather it stops growing. Option C is incorrect because hair turning grey is a natural process that occurs during the aging process and is not specific to the catagen phase. Option D is incorrect because although the hair follicles do shrink during the catagen phase, this is not the primary change that occurs.
