Any Tips for First Time Shaving Head?

[BMTridge]

I've been on finasteride for 9 months now and experienced a vicious 3 months of shedding which seems to finally have stopped. However, during that time I lost a lot of my thickness and have been hiding what would be a very noticeably diffused hairline with a long fringe.

For now I've somewhat accepted it's not really feasible to keep my hair this long and am on the verge of shaving it all off. If I cut it much shorter it'll really just be obvious and I can't be bothered with that.

I'm a bit worried that I'll be surprised (in a bad way) at how serious my hairloss has been since I haven't had my hair really short in a long time and shaving will show off the patches. I've also never really had a buzzcut so I can't even imagine how the change will be for me.

Any tips from anyone who has shaved their head for the first time?
