Hey :D So here are some ideas that comes to my mind (well i know it´s not that "historical accurate"):

1. short slicked back hair (like Albert Wesker or Alfred Ashford from Resident Evil or in 1920s/1930s) (example: https://www.deviantart.com/mister-ashford/art/Alfred-Ashford-567803866 or https://www.evilresource.com/images/data/full/remake/albert-wesker.png)

2. Short side-parted hair (also like in the 1920s-1940s) (example: http://up.picr.de/6859711ksb.jpg)

well i know that thats probably some strange suggestions bet yeah thats my favorite Haircuts xD

Would you be able to do a haircut that hides half of the face with a side-shave?
