Yes. I suffer from head sweats, especially during the night. They are horrible, uncomfortable, and as you said... embarrassing.
In the past I've tried everything, including antiperspirants made especially for the face - and even they didn't resolve it.
I have recently switched back to a very low carb diet, and I've noticed that the head sweats are less. I do get them, but not so frequently. I think it could be related to blood sugar levels.
How is your blood sugar?
