Excessive underarm or arm pit sweating is an embarrassing condition for many women. It can also be coupled with excessive sweating of the hands or feet (see my article on getting rid of these conditions as well), this article will give a simple solution to underarm sweating treatment for women that is cheap and effective.
First, you'll need to go to the drugstore/supermarket. Go to your deodorant aisle. You will first need to purchase some men's deodorant. I recommend Mitchum for Men unscented gel (unless you want to smell manly, unscented is the way to go!).
Next, you'll need to examine the women's deodorants. You need to find one with the highest percentage of active ingredient you can find. I like Secret's invisible solid. Don't waste your money on the clinical strength products. Compare the ingredients and go for the highest percentage of active ingredient.
Next, time for the fun part, every night before you go to bed, you're going to take a warm/hot shower. You can even wash your hair and not shower the next morning, whatever you want. When you get out of your shower, put on the men's Mitchum to sleep in. By showering, you open up your pores and by sleeping in the deodorant, it gives it time to sink in. The next morning, if you shower again, don't use soap on your underarms or shave (do that at night). If you decide not to shower in the morning, you don't have to wash at all. For the daytime, put on your women's deodorant for the day.
Finally, within a few days to a week, you will see a noticeable change. You will sweat much less. Continue putting on the Mitchum deodorant at night and your choice during the day for as long as you want, if you stop treating, the sweating may come back full force, but you can always build up your resistance again. Good luck!
Tip: Many women's deodorant manufacturers are now selling very expensive "clinical strength" deodorants, you don't need to waste your money on these products as the steps outlined above work just as well if not better than these.
