I'd never really thought about hair loss products for men until my dad decided years ago that he wanted to cover a bald spot. I don't know what made him decide to cover it, but I do remember he bought this can of powder spray to match the color of his hair. And I remember that stuff ended up all over the place, on his pillow, the couch, chair, etc. It was a temp fix and a big mess.
That was years ago however and since then, I'm sure products have changed, at least I certainly hope so!
