Well, I'm not sure if headshaving is a drug, but I know for me it is an addiction. I have decided a dozen times to grow my hair back, but return to shaving bald after a week or two.
I have made some changes, like losing weight and dressing better. I think my biggest change is in attitude. I used to worry about what other people thought about how I looked, or what I did, but I no longer worry about those things.
Bottom line, I think people think I look much better with a full head of silver hair, but I like how I look and feel with a shaved head, and enjoy my daily shave.
