Hello, and welcome.
I'm a big sweater too. I've suffered with it for years until I came across a product called Certain Dri. You can find it at Walgreens or basically any other drug store. I'm not sure what to say about head sweat other than, like the others said, maybe a hankerchief, but if you have a big problem with underarm sweating, try Certain Dri. Honestly, NOTHING worked for me until I found this product....and I tried EVERYTHING. I'm so much happier and more confident because now I'm always dry and I can wear any shirt I want and don't worry about sweating because I dont anymore.
Hope this helps and best of luck
