sounds like a fungus...maybe try something like nizorol or selsun blue [but make sure she doesnt get it in her eyes]

Since it's been ahwile you've probably already found a cure and/or it's fixed itself. But I just read there's a sulfur soap that takes away the smell. My daughters hair generally smells nice but last night, after showering, it stunk. I was concerned she may have internal issues but come to find out it's likely a fungus. I vaguely recall her havhing this issue previously and it just went away. At that time I thought I may have re-used her towel 1 too many times. This time I double checked the towel issue and the towel is just fine. It's definitely her because her brothers hair smells fine! I'll just have to keep an eye on her for the next couple of days! :)

One of my daughters had the same problem. I asked her doctor about it..he sniffed it..said hmmmm..and not to worry about it, it would go away. I stopped worrying about it and it went away on it's own. I guess that's not much help, he didn't give me any ideas as to what could have caused it...just nothing to worry over and something that would go away on it's own.

I've had this problem for the past year... it is so frustrating! I've tried Selsun, H&S and Giovanna Tea Tree shampoo and conditioner with no luck.

However, in the past few days I've been trying Tersaseptic ( http://www.stiefel.ca/tersaseptic.php ) and it seems to be working well!!! I highly recommend trying it.

Good luck with this.

Is the weather hot where you are? She might be sweating a lot on the top of her head. It is also worth checking if she has a fungal infection or exzcema.
