Man! As tempting as it sounds having a smooth bald head and not having to worry about shaving, I'm still reluctant to do it in case I do want to regrow my hair. If I was balding, I would do it and not "fight" it.
After 5 sessions
I stumbled into this group while researching this very question. So far, I am very happy with the results my first laser experience. I'm naturally bald on top have shaved for over 10 years and now am having the remaining horeshoe fringe removed by laser. The first treatment was 2 weeks ago (with a test patch done a week before that) and my hair is much lighter and thinner. The shadow is much less pronounced when shaved and hardly noticeable even after a few days growth. I'll post more later if anyone is interested... gotta get back to work.
