Actor Mark-Paul Gosselaar’s Mature Hairline

Hey doc,
I was trying to find a good example of a hairline going from juvenile to mature and I found actor Mark-Paul Gosselaar, better known as Zack Morris from Saved by the Bell (kid/teen show in the 90s) and later he was a cop on the show NYPD Blue.

For someone like me in my 20s I think it serves as a good example of what a mature hairline is. Would you agree?

I know you’re all shocked to learn that I didn’t pay too much attention to teen sitcoms in the 1990s and thus am not familiar with Mark-Paul Gosselaar… but I absolutely agree that this is a great example of a young man’s hairline maturing.

Note in his teenage photo on the left that his hairline is squared in a typical juvenile hairline. In the photo on the right (I assume taken 15 or so years later) the hairline is a classic example of a mature hairline. Just based on photos I’ve seen, this man appears to have a great head of hair.
