This one is dedicated to my buddy, Zephyrash. While there are lots of hairstyles available for sim women, there are relatively few for sim guys. And for sim men of a certain age -- forget about it. After fiddling around in Photoshop, I figured out how to make a
realistic receding hairline. It's available in all four of the standard colors. Elders have the usual gray hair.

The nice thing about this style is that your sims will have hairlines that gradually recede. Teenagers have normal hairlines, while young adults see their hairlines creep a bit upward. By the time they hit adulthood, their foreheads have a lot more real estate.
What do you think, Zeph? Something you could use?
