I believe that kind of product depends on the individual.
As a woman who has been around for several years, I can say that a lot of times me worry more about it that the women who care about them. I have been involved with a couple of men who started adding early, but for me it was a non issue. It was their behavior that exhibited the youthful vitality which attracted me.
I realize that for your own benefit you probably want to try something anyway. I’m just pointing out that until you find a product which works for you, try not to stress out about it.
I have been seeing commercials for a ball cap with lights inside which supposedly enhances regrowth. I laughed when I first first saw it, but became curious whether there is anything to that.
If you or anybody reading this tries it, please share the results. If it makes a difference that would be pretty cool, no mess. Hopefully there is no risk of the battery bursting into flames like some phones!
