If it looks like shit it grows back. I’ve been doing my own for a year and 90% of the time it’s acceptable after about 3 tiktok tutorials! And if all goes wrong you can still go to the stylist after lol
It’s a good skill to have and if you go slow it can’t go THAT wrong**! even if you do a bit of a bad job it’ll grow back nbd *only if you already have bangs
** results may vary
