Todomomo

Rei has rapunzel hair so Momo usually has to help blow dry it and a bunch of other things.

Kirimina

Mina can't do her own hair. Kiri has to do it.

Miruhawks

Rumi. Dove might have straight(lies, it's a bit wavy.) hair like her, but it's thick and there's a lot of it, so Rumi has to do it or Hawks breaks a comb.

She got the wavy hair from her grandpa

Iidamei

Iida, Mei has dreads so she hasn't had to really Comb her hair in a while.

Kamijirou

Neither-

With Jirou's bangs I won't let her touch my hair. Denki is just gonna make it frizzy

Dabi X toga

Dabi did fuyumi's hair so he does his son's hair when he needs help.

Nejitama

Both of them can do their hair so they can do their kids hair pretty well.

Mt.Kamui

Yuu does Okuri's hair.

Ryushot

They both can do it but since Megami has longer hair that Ryuko has never had experience in doing anything with, so Shinya does Meg's hair, Ryuko does Daenerys's hair.

HitoRei

Shinsou does his hair like that. He knows how she likes her hair and does it until she knows how to do it. (He cries when she said she was fine doing her hair alone.)
