I'm 53 (years young), and I would think females of any age never, ever stop caring about their hair. They may neglect everything else (and shame on them if they do), but as someone who is meticulous with her appearance--as much as I can be--hair loss has been by far the worst thing about middle age. But you asked about older men: My husband is 60, quite thin on top and has recently started using minoxidil, which he should've done five years ago. He still brisk walks and works out, and I'm sure he's going to care about his hair and physique through his 60s and beyond. On another note, my older son started balding when he turned 18 and hopped on finasteride six months later. He's 21 now, but he's still thinning diffusely.
