Actor David Tennant’s Mature Hairline

I’ve always been curious regarding the UK actor David Tennant. He’s 41, and has a very good head of hair, but I can’t work out if he has a mature hairline or not? I’ve looked online and found some pictures, so was wondering what you think?

Here he is when he’s younger, I reckon he’s about 20/21 or something. – Photo

Then these are, I’m guessing from over the past 10-15 years, the last one being last year, and the one before being around 2009. – Photo 1, Photo 2, and Photo 3

To me, it looks like he has a mature hairline even when he was young?

I’m not familiar with his work, but IMDB tells me that Scottish actor David Tennant might be best known to US audiences from his starring role in the television series Doctor Who.

He has a strong mature male hairline with a widow’s peak. There is not sign of erosion, suggesting that this will last him a long while. This is not a hair transplant.
