I am 34, and yes I take Proscar.
If you are using meds that will help prevent you from going to a NW5 or NW6, but lets say the worst case scenario happens. You have a procedure for zones 1 and 2 for say 3,500 grafts…
So you have had your procedure for the front and are on meds which help maintain your crown thru your 30’s and 40’s, you get to enjoy a great full head of hair in your 30’s and 40’s
Now say as you get older the meds wear off and your crown starts thinning, you may need to and should plan on a 2nd procedure for the crown, zones 3 and 4.
Take my case for example, I have had all 4 zones done with 6,400 grafts and you see my result, I have enough left in my donor for another procedure later in life should I need any area thickened up.
Again, you came in for 3,500 grafts for the front, then you come back for a crown procedure years later… Now see the model below.
Take someone such as yourself who has never had a procedure before, and Dr. Armani asses that he can harvest 8,000 grafts from your donor area over time.
You eventually need coverage from front to back, here is how it would be managed roughly:
Here is what is recomended to the patient
Zone - 1: 2500 follicular units at 80% density
Zone - 2: 2000 follicular units at 40% density
Zone - 3: 1240 follicular units at 30% density
Zone - 4: 2030 follicular units at 20% density
Total grafts 7,770
This strategy gives a high density front with a full dense hairline with many styling options and a lower density crown with great coverage.
