Here are what you’d find in the “Modern” Packs as far as hairstyles are concerned. Note that you can use hairstyles from other packs with modern characters provided you are using season 2 packs (that’s why, in this case, Season 2 Supers and Sci-Fi characters are using Modern hairstyles but Season 2 Fantasy and so on would have worked as well 🙂 ).
Season 1 packs are independent.
These are all hairstyles from Season 2 “Modern Male” packs (ie: Modern, Supers & SciFi)
And this is the Season 1 Modern Male pack from a hairy perspective 😛 :
Hope it helps. 🙂
