The fur growth depends on the stage of moult regrowth the hamster is at. It can take a few weeks for growth to start then up to a couple of months for the full coat to come in. If she is having hormonal issues then it may not regrow fully but as long as she is comfy and active then that is fine.
Yes I know the roads of Huddersfield very well and the neverending digging associated with the gas pipes
In fact the road past my vets has been closed for weeks for roadworks but luckily you still have access!
