Male long haired hamsters can have extremely long fur!There's no guarantee of length with individual hamsters though.
As for maintenance,it shouldn't be difficult as long as you use a substrate that does not tangle in fur.That said,wood does tangle in fur,while Fitch and other paper substrates really don't!It wouldn't hurt to switch to Fitch regardless,being a cost effective superior substrate that is much safer than wood substrate with many benefits like never being capable of causing an allergic reaction(wood can,even if not immediately seen)
