Styling the hair of a ToTs 2018 mask

I just got my ToTs 2018 mask but the hair on the back is messed up and they used a strong product in the hair at the top of the mask and some hair is glued to the neck on the back. Any tips and suggestions?

Looks old & decrepit like a 40 year old mask should

It’s not styled like the movie though which bugs me

Gurl you need some weave up in there!! That would be tight!! Lol I cut off the neck hair on mine when I had one

I actually washed mask and hair in hot water…then air dryer…I like the look now…looks kinda like a grimey warlock now…
