1) I live in the Caribbean (Dominican Republic) so it´s always hot and humid all year long. I even sweat without doing anything at home
2) I suffer from hyperhidrosis (excessive sweating).
3) I play tennis at a NCAA Div 1 level about 4 times a week. Love to do outdoor sports, go to the beach, go to the pool.

I´ve been using proThik to cover my thinning hair. Im thinking about getting a system, but I want to hear your opinion first regarding my excessive sweating. I decided to stop using proThik because my hair has gotten thinner and thinner to the point where trying to cover it up looks a little ridiculous now. But also because my scalp becomes a mess after a workout or a swim and I start messing everything (pillow, clothes, towels, hats) I touch with brown dust.
I know TopLace claims that sweating and swimming is no problem, but so does proThik in their page.
What do you guys think? Is it worth it for a guy like me to get a system? If you are a excessive sweater please advise.
