Most attractive hair style on the gender you are interested in

[YPrrrr]

Curly hair on guys. Dark hair whatever length as long as you can run your finger through it.   

You have good taste

[FAMY2]

You have good taste

You have great hair.

[Walter]

Oh you too.   

Thank you.

[Classic]

Long straight hair is sex.

[Thyme]

Long straight hair is sex.

Yet another thing I can put on my list of things I can tease you about.

It doesn't look too good on me though. I'm getting them cut pretty soon, for my own ease but also for JOB QUESTAN.

I like long, straight hair best. Wavy can work fine, depending on the style, and so can medium. I also like the darker colors, like brown and black, over the lighter colors like blonde and orange.
I have the same taste in hair for myself and for a girl.

[Skylark]

boy - i don't care honestly but I voted short and curly
I do not find long hair attractive (most of the time) and I do not like straight hair much either.

girls - it's not like that.

[Selkie]

I don't care, just as long she keeps her hair natural. Hair straighteners make me die a little bit on the inside.

Me too. Literally. My mom and my sister insist on putting the thing on our tiny little bathroom sink and I always burn my hand on it/drop it on my foot/etc.

Can't stand curly hair.

[Lotos]

Medium-long and wavy or straight.

I'm not interested in those genders.

Males and females can both have a FoS haircut.

Males and females can both have a FoS haircut.

Well then I guess I'd have to say yes until I see a bad example.
