I'm trying to figure out how the SIL being "unattractive" is relevant to this story...

Your beef is with your husband. If you don't like how the kids' hair is being treated, you need to take it up with him. He is the one letting his sister mess up their hair.

Or, maybe it is relevant in that she's using unattractive to mean her SIL doesn't have any hair, doesn't know how to grow/care for hair, and therefore shouldn't be messing with her daughter's hair. JUST KIDDING! lol
