I recently started using Gillette 3-blade razors. They are doing a pretty decent job. In boy mode, I used to use an electric shaver. It didn't get it nearly close enough.
I already started laser last fall, so most of the dark hairs were gone. I am doing more laser now, in between electrolysis sessions, to keep the dark hairs gone. So I don't have a lot of shadow even with some stubble showing. Everything that is left is white.
That is important to me, since I am going full-time at the end of this week. I'll still need electrolysis for at least a year, so three days a week, I can't shave. Talk about dysphoric! But there's no way around it. I have two more laser sessions in this round, but I'll do more again later if the dark hairs come back.
