Looking for oldies Shoujo...

Hi guys, I’m looking for the title of this school life shoujo where the girl is neighbours with these 2 brothers (one is a rebellious boy with spiky dark hair, the other is the gentle intelligent everyone’s fav blonde tidy hair boy). The girl was a nobody, and has a crush on the blonde boy since the beginning, was rejected(?) and was helped by the dark hair or something I forgot. And the girl later revealed to have a skill in hairstyling which later become her job i think? Anyway if any of you know the title of this manga, I would really appreciate if you share, I’ve been looking for ever!
