Although Botox is used for hyperhydrosis of the axilla and hands, I suppose it could be used for the scalp. However, normally 100-200 units is used for treating the more common areas. It may be a bit too much to try to treat the scalp, and I am not sure if it would work well on such a large area.

There is no question in my mind that Botox would work for hyperhidrosis of the scalp. One would run into the problem of dosing. You need fairly high doses of Botox injected in a relatively small area to effectively treat hyperhidrosis. We routinely perform a starch test before injecting Botox for this problem. It is quite possible that the test would show the scalp hyperhidrosis to be coming from a small area and not the whole scalp. In that case I'd feel encouraged to treat. My suggestion is for you to consult with a physician willing to try this.
