Make sense of the problem
What matters before you choose a solution
External vulvar care and vaginal symptoms need to be separated. The vulva is external skin; the vagina is internal and self-cleaning. Odor, discharge, itching, burning and dryness can overlap, so the pattern and accompanying changes matter.
If you notice a stronger smell after a workout but no other change, sweat and damp clothing may be relevant. If the odor is new and comes with changed discharge, itching or pain, simply washing more is not the same as solving the cause.
