I have difficulty using any soaps (soap makes me very ill)...so I did a search today on soapless shampoos etc. & got this site http://www.purebodyproducts.com/
this site claims that you can use borax as a shampoo (diluted of course) followed by a citric acid rinse...I've never heard of this before...
so I did a search on "uses for borax" & found this posting!...
so I haven't experienced using borax in this manner but it's a very interesting use for it...
please note I do not own the above site @ all nor use their products...just searches on both topics lead me here...I thought u might find this interesting...
