hello dr. armpit, i struggle with a very strong body odor that sometimes smells of onions and have been struggling to find a remedy, but I recently started using dandruff shampoo as a soap for my armpit area and have found that it works really well with combatting the odor. I leave the shampoo on for an extended time before washing off. The odor does still come back eventually although I shower daily. It is very interesting though. Do you have any idea as to why this dandruff shampoo (head & shoulders) may be working? Best
