Progression of Hair Loss
Generally, a young man who is a Class 4 by age 21, will probably be a Class 6 by age 30 .Sometimes there is not enough donor hair to transplant the entire head once one projects the size of the future balding area. Nevertheless, there is usually enough donor hair to do at least the hairline and the entire top of the head, leaving only a round spot in the back if there is not sufficient donor hair.
If years go by and it turns out there is sufficient donor hair and the pattern is not as rapidly advancing as was suspected, at least a modest coating of hair can be put in the crown or vertex of the head, which will present a very nice appearance.
When beginning transplanting on young men, it is best to decide where to put the hair line based on previous pictures, family pictures, and with the sense of what will gener ally make the person look the best. It is not necessary to create a receded hairline look in young men .There are plenty of men who have non-receded hairlines well into their sixties, the author being one. Note the pictures of the author’s grandfather, Dr. J.T. Waggener, from age 28 to age 100.
Dr. Waggener’s hair was quite thin at age 100, but with very little hairline recession present .Note that this thinning of old age is what is termed senile alopeciaand probably results from the falloff in thyroid hormones and growth hormones in later life. It is notmale pattern hair loss. If a young man has lost his hairline, it is not too early to put him on medical therapy and rebuild his hairline with a hair transplant.
