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.
That’s because you’ve shave that hair for 20 years.
Hair that isn’t normally shaved poses a greater risk for ingrown hairs.
To reiterate, in grown hair in your armpit is awful. It will get infected unless you wear tank tops all the time, and an infection near all the nerve endings in your arm put causes for a seriously painful time. It can all be avoided by just trimming without going down to the skin.
If you do go down to the skin on an area you’ve never shaved before, you’d be wise to do so using conditioner on your armpits instead of shaving cream. You’d also be wise to apply aftershave afterwards.
But you’re right. Just as most men don’t get in grown hairs in their face from shaving after the first 3 or 4 shaves, you are fine, given that hair in your armpit is basically expecting to be shaved.
