is there a hair/fur tool in houdini=?

No there is not. Think you can emit particle lines from a surface and use particle dynamics on them. That is as close as you can get to fur/hair.

how good is this solution you mentioned?
and are there any other possibilities (i.e 3rd parties/ plugins?)

Don't expect to be able to braid hair and such. I don't know of any plugins but I would shocked if you could not export it to some other Fur Animation System.
