Taoist soap is used for inflammation on the scalp as well as thinning hair, but thinning hair is a complex problem. The soap will help, but you need to make sure your sugar intake is low to zero, as inflammation feeds from sugar, when thats done, the localized inflammation can be taken care of taoist soap.

the only con for it is probably getting out of stock very often. but just keep your collagen intake high, and exercise enough with scalp massage (i hope your acupuncturist also told you these) to get the best results with the soap.
