I was disappointed by the rooted hair, mostly because of the poor quality of it. This isn't the natural fibre wool kind of hair we're seeing on artisan figures today, but something like the thin polyester strands we saw on dolls and other 1:6 figures in the past. At least that's what it feels like and how it behaves. The hair is easily messed up and left with flyaway strands. I can imagine it fraying and puffing out over time, like most synthetic fibre doll hair did. I already have a few strands out of place that won't go back to their position. Static really seems to adversely affect this fibre. I'm just hoping it holds up over the years, but do think sculpted hair would have worked fine. Maybe sculpting a bob haircut style isn't EXO-6 strength, and if they tried it would have turned into a helmet head, sort of like their Janeway figure.
If you use some hair product that will keep hold the shape of the hair and control those stubborn strands.
