Figure 2 legend:
Women with stage 1 and 2 hair loss tend to present with either episodic or continuous increased hair shedding. On direct questioning most agree there has been a reduction in the volume of the hair when held in a ponytail. Women with stage 3, 4, and 5 hair loss may present with either loss of volume of hair over the scalp with widening of the central part, episodic increased hair shedding, or continuous hair shedding.
