There is a prominent difference between Nazi and curtained haircut. The parting in Nazi haircut is in on the sides e.g. right and left. And the bulk of hair distributed on either side.

 

Brendan Fraser has used curtained hair in most of his movies with parting in the centre.

 

The sides and back in both the hairstyles become small while at the top it is long.Nazi haircut has been used a lot in world war and other movies. For example Brad Pitt sported one in Inglorious basterds and Tom Cruise had it in Vakyrie.
