Hi Everyone, I have found a solution that works for me. You need to follow all the steps otherwise it won't work. First step: Pluck your armpit hair. This a must. If you can't stand the pain, pluck it one by one. Don't use wax or something. I use a hair plucker. Second step: Take a bath using soap. I know that everyone's in here has a good hygiene. So, I'm not trying to insult you guys. Third step: Use Alum or Tawas anything that is available in your country. How to use it is just rub it after to your armpit after you take a shower. So basically, you rub an alum to your armpit while your armpit is still damp. You can rub the alum for 4 motions of up and downs for each armpit. After rubbing your armpit, you need to let your armpit dry with air and not wiping it with a towel. You will see a soft white coat on your armpit after your armpit dry. if you can see than you will notice that alum has created a white layer on your armpits so that the bacteria wont thrive. Now, after your armpit gets dry, you can use clothes. If you feel itchy or burn on your armpit, don't rub it and stop rubbing alum for a while, let your skin heal for couple days.
I know you guys won't believe me. But, the combination of having a hairless armpit and using alum works very well. If you don't pluck your armpit hair, using alum will be useless. Good luck everyone. If alum/tawas doesnt work in the first 3-4 days. Just keep using it, because your body needs to adjust to it. After 4 days, it'll work magically.
