Hy, i also suffer from hh in my underarms so i can understand you. To be honset i have never heard that anybody has you problem. But in the end it is the same thing, no mather where it may be.
You have sad that you have tried antiperspirants, but they did not work, same here!!!
The worst thing is that i am ashamed of it and hide it as better i can, i dont want anybody to see my problem.
I know that this attidute toward hh must be changed but i cannot help myself, i cannot just let it be!
Stay well!
