I was talking about hygiene with my partner who is a nurse and they were telling me that a lot of people remark that their armpits are smelling worse than normal and they are using more and more deodorant and people just think it is normal.
Trichobacteriosis looks like a yellowish coating on some of your armpit or groin hair and you need to shave and wash the area every day for 2 weeks. It is more common in men than women in the US only because it is more common for women to keep their armpits shaved. Most of the patients who are affected by it think that its actually residue from the increasing amounts of deodorant they end up using.
Aside from trimming, you can also wipe with an anti-bacterial wet wipe when you notice you stink worse than usual. It resets the biome on your skin by wiping out the bacteria. Don’t do this everyday though. Just whenever you feel the smell is getting worse.
It’s crazy that we have so many good, symbiotic critters living in and on us.
