I am a 34 year old male, what do you think of my hairline?

The hairline should be V-Shaped as this is a typical hairline in a Caucasian male whose hairline has matured (bottom photos). Unfortunately, your surgeon gave you a rounded female hairline by shape,  The leading edge of the hairline should have a transition zone in front of the two and three hair grafts so that there is no visible hairline present (the three last photos), just a zone from the forehead to the thicker hair. You have no such zone. Compare your hairline on the left with the three photos at the bottom of the window. This is a typical mature male hairline which has a better shape to it.  In all of our patients we create a transition zone in the front of the two and three hair grafts as as shown in the three pictures at the bottom which demonstrates a ‘no-hairline hairline’.

How does finasteride/dutasteride affect your predictions of the hair loss pattern in an 18 year old? Does it change the pattern or do patients follow the same pattern but slower?

These drugs slow the advancement of these advanced patterns provided that the genetics are not very aggressive as with the young men who inherit a Class 7 pattern that starts appearing at 18-19 years of age. In these young men, we just don’t know if their hair loss pattern can be stopped in its tracks, but there is never a harm in trying.
