Does the Entire Follicular Unit Miniaturize or Just Individual Hairs?

Doctors say follicular units contain 1,2,3, and sometimes even 4 hairs per unit. My questions is, when miniaturization occurs, does the whole follicular unit get affected at the same time or does the individual hairs within the unit miniaturize at a different pace and time frame? Hopefully my question is clear.

Best regards! I know you keep busy with the blog and practice!

When miniaturization occurs, each hair within the follicular unit seems to have its own time clock, but the follicular unit itself will miniaturize in the patterned area at a different pace, area by area. Often in young men, the frontal hairs will miniaturize faster than the hairs on the top of the head, about 4 inches behind the hairline. As the hairs within the follicular unit miniaturize and it progresses, one hair at a time may drop out and die before another one within the follicular units takes its genetic course.
