I'm going to counter this neutrality by evaluating the casts hair.
Faye I couldn't imagine with long hair. Looks good, fits her and I've always liked short hair with glasses. Although...
Tai pulls off that look better. She's got the small and androgynous thing down.
Dora's current hair looks good, though it doesn't stand out too much and I hadn't really thought about it until I decide to judge everyone based on hair.
Marigold looks fine with hair down, cute with it in a pony tail and, though it's admittedly probably a fashion don't for a grown woman, super cute with pigtails.
Emily looks better with long hair, though short hair probably fits her better. Doesn't seem like the 'spend a hour on her hair' type. That's time that could be spent catching mice for your true love. For the sake of variety maybe he should have kept it long anyway though.
I don't know if Hanners messy hair fits her or contradicts the ocd, but I like it.
I like Veronica's new hair. Looks younger, though I don't know how much of that is the hair and how much is how she's being drawn at the moment.
Claire with hair shading has the best hair. Claire without shading still has the best hair. But not by as wide a margin!
The guys? Who cares about the guys? I guess Dale's hair is pretty cool. Now leave me alone!
