Comments have word limit so i will send in pieces. You lose 30% of your body heat through the scalp, which is why it sweats so much. You can actually apply the antiperspirant all over your scalp since there are sweat glands all over. Use a gel stick, unscented probably, and apply a small amount to your fingerstips. Massage directly onto scalp to avoid gunking up the hair. For maximum sweat prevention use a cocentrated aluminum chloride (active ingredient in all antiperspirants ), product like drysol. You apply this the nite BEFORE and it essentually shuts down the sweat gland completely. One less thing to do when you're getting dressed! These products are good for sweaty feet too and can be applied daily for a week, then weekly after that for long term dryness. If this sounds unhealthy to some, you have thousands of glands elsewhere that will compensate. NOTE: With zero sweat this area will be VERY dry and subject to chaffing in friction areas like underarm and groin.
