receding hairline at 20? advice please?

Okay so my hairline is like at male pattern baldness one.

Eventually im just going to shave it down to a grade 1 on the clippers…..I have a nice masculine face….so it should suit me.

I have had long hair for quite a while…..i think everyone is going to be extremely shocked…..when i go from long bangs to a short buzz.

Im not that bothered to going bald myself…….but i think the expression on everyones face….and comments…..is just going to kill me

Any adivce?
