I am 61, my younger brother is 60. He used/uses these products (I think in combo). He still has some hair, while I look like Uncle Fester.
If I remember correctly, he did have side effects like low libido but did not care. (Just a joke here) He's more attractive to the ladies but wants them not. The women shun me, and I'm interested in them....
In reality, I don't find that having a bald head has any downsides what so ever. I love it and many women do too.
Is is my first choice, maybe not. But in the end it is nice and easy to keep clean and I've come to really like it. I've been bald since age 33. Being bald confident and muscular back then was absolutely an attractant.
