Balding without miniaturization

Hair grows in bundles called follicular units containing from 1-4 hairs each. When some people lose hair, the lose hairs within the follicular unit occurs so a three hair follicular unit might lose a hair and have only two left. Then in time, it will lose another hair and have only one hair in it.  Eventually that last hair may fall out as well.  This occurs all over the scalp in the balding areas in many men without miniaturization. The average human scalp has 50,000 Follicular Units of which 15,000 are in the rim around the back and sides of the head and 35,000 are subject to the patterns of balding you inherit from your family. The 15,000 follicular units around the side and back of your head are not prone to balding, keeping their hairs over your lifetime.
