I'm 54-staring-down-the-barrel-of-55, and it seems like the older I get, the shorter my hair gets. Yikes--by the time I'm 60, I'll be bald.
.................. And I love it! It's straight straight straight, but after I wash it and let it dry a little, I apply some stuff my hairdresser sold me: Redken Rough Paste. It's sort of like toothpaste you put in your hair, and it lets you spike it or piece it or whatever you want and it's repositionable. After a ride, I take off my helmet, towel dry my hair, then fluff it with my fingers, eh voila! Decent-looking hair. Sure I'm still a major sweat machine, but my hair looks good.
