I'm 5 days in with 3 shaves under my belt. So far so good. I'm 33 years old and struggled with hair loss and the overall idea of "aging" for last few years. It really takes a toll on your mental state after a while. Shaving my head was rite of passage for me. Liberating? Yes, but more of a transitional state of who I thought I was to who I really am.
My transition into the shaved head was slow. I started with fades and then moved into the "high and tight". From there it was a #2 buzz cut. Then a number#1. Finally, no guard. This whole transition was probably a little over 2 years. I gave me the chance to digest it. It was still a rollercoaster ride of emotion, but a good decision in the end.
As far as reactions go. It's a mixed bag. More positive than negative. A lot of people, I believe, are just naive to other people's situation and tend to ask "why." That can come off as a negative reaction, but I truly think they just don't understand. And, unless you're dealing with hair loss, you probably wouldn't. It's a very personal thing. In the end, I like it. People will get used to it.
My goal now is to "own" my bald head. I want to enjoy it. I want to be proud of it. I don't want it to be something I have to do, but something I want to do. This may come with fancy razors, shaving soaps & hot towels. Whatever it takes, I'm invested.
