You can get them made so they are already short enough to where instead of going to a salon for the whole big cut in you can just make a trip to your barber for a blend in type cut.
To the OP, yes I have seen them and all the tutorials and yes they are amazing these days. Would certainly boost my confidence with my ever growing receding hairline and let me tell you i'm probably the last person on planet Earth that could pull off the bald head look. (tall/thin/lanky/larger than usual forehead in general/big nose, etc)
That being said the very harsh reality is that whether it looks 1000x better or not, most women would simply find the idea of their man/a man who wears one to be bizarre, extremely non-masculine, or downright shocking(not in a good way). Now if I did have a secure girlfriend who supported me through it 100% I'd probably consider it one day but to have that kind of conversation with a chick on a 4th or 5th date before we f-cked (so she doesn't grab on the damn thing and ruin the hairline), I just don't know how I could go through that kind of awkwardness. Maybe one day they will begin to become more accepted, but it probably won't be in our lifetime IMO.
