Please help :c . I remember that it talked about two school boys, one of them always had bed hair and the other used to fix it for him at school (I don't remember if he wanted to be a hairdresser or it was a family thing)
Thank you :c

Probably not it but Endou-kun no Kansatsu Nikki has some hair styling elements.
