DearCustomer thankyou for your explanation.
I understand you don't plan on the Goo Gone on the scalp itself.
In this kind of situation if the bottle does not say it's harmless and it's ok to use on a human I would call the company if I wanted to use it on a child.
They may also tell you whether or not the product does take care of the glue issue with the nits.
I fully suspect it does an excellent job considering the testimonials at the website below of Homax.
Here's their website (GooGone is made/handled through Homax) and there's a phone number,address and email you can ask if it is 100% safe for your child.
I tried to find an MSDS sheet at the website but they don't list that one for some reason.
It was found at National Institutes of Health.It is not just "citrus."(see botXXXXX XXXXXsting in MSDS info)
The product below described how it first dissolves the glue of the nits.You may want to check this out:
Please let me know if I can be of any more help?
P.S. As always even if it looks like a "go" on this product do remember to test it one day on your child in a small strand of hair and give it time to be sure it doesn't cause her to break out or have a reaction.
