I'd be happy to take that. Which hair systems are you interested in?
I've implemented support for Hair and Fur and Ornatrix plugins some time ago.
Or are you thinking about dedicated object modifier like fuzzy?

Personally I think it would be great to support 3rd party hair plugins (ornatrix), but we should start adding support to 3ds max native hair tools.

@jjeziorski it would be great if you hangout on the Discord server

There is an open PR for hair additions to appleseed which needs to be reviewed first.
Once hair support and the OSL hair shader is added to appleseed-core it can be exposed in Max as well.

Curves are already supported by appleseed, it should already possible to emit them. Once the hair shading PR is merged, we can take care of this aspect.
