Tenant Shower Head. My responsibility?

[Rami W.]

So my tenant has a "broken" shower head. More like its clogged. Asked her to clean it and she said it doesn't work still. The tenant and shower head have been there since I purchased the property. It is one of those kinds that detach and extent a few feet with a hose. I assume they put it on at some point before I got here. If I am responsible, I am just going to replace it with a standard lo-flo head with no extension.

Or should I replace it with a similar model? I know she has a young child that she probably uses the hose to bath with. Is it something I should ask them to help or pay for?
