How to get a horsehair crest to stand up straight

[Fhyn]

Hi folks, got a new corinthian for my SCA fighting, and it came with a horsehair crest. Problem is, its well laying to the side and not straight up, like I see everyone elses.

Now this isnt a problem, if they can also be like that. But if not, then I need to figure out, how to get it back to standing up straight. First thing that came to mind was wax, but since I have never done this before, thought I would ask here first.

Here is a pic of the helm. Thanks
