And FFS, people need to clean their asses.

I have a mild allergy to most deodorant so I need to pick my battles, because if I wear the stuff that actually works daily, I'll end up with a pretty sensitive rash and unable to wear anything at all. So most days I'm either wearing nothing or the crystal stuff which last like 45 minutes. If I'm getting on a plane or in a crowd I throw on the good stuff. Also I'm not paying $20 for Native BS I'd rather just smell bad.

Sensitive skin issues. I haven't fully figured out which ones are good or not, but my armpits seem to tolerate only roll-on format deodorants. Aerosol ones will give a burning sensation and rash within 1-2 uses and stick seem to just give rash within 3-4 uses. That actually did got worse after accutane treatment, but helped to figure out that only roll-ons are suitable.

But during current heatwave, theres nothing i can do. I sweat a lot as soon as temperature starts to get above 24c.

When working out, I'm literally the sweatiest person in the gym and start to smell of ammonia within 45-60 minutes. Up until now no one hasn't mentioned anything, but i am paranoid about it and whatever i should deal with it or not or even if i can.

Idk who needs to hear this, but some people have body oils that react to the ingredients within various deodorants that makes the smell worse rather than masking it (which might be why some people are adverse to it). Some people who have had poor hygiene in the past have difficult bacteria cultures that won't go away just by soap and water.

Try changing deodorant to antiperspirant. Minimize any perfume or scented products. And if soap isn't working, acne face wash works great (just don't use it every time or it dries you out).

We survived a few thousand years or so without deodorant.

If you shower daily and wear clean clothes, you shouldn't need it.

I find modern deodorants to be a bit overkill on most days. They are slimy, they irritate my skin, cause acne and take forever to wash off later. Antiperspirants are even worse. I really only use those types of products if I'm outside in humid heat after not showering for a day or two, once the stank has had a chance to build to noticeable levels. And yes I've checked with other people who have no problem providing critical feedback.

For me, those products are a solution looking for a problem, but for others, they might be essential. Some have need for even stronger versions that might need a prescription. Everyone produces different levels of stank. It also depends on the social expectations where you live, your climate, activity level, and diet.

After weighing the various factors, your decision to use any product that goes in or on your body is a personal one. People don't have to use products that don't actually help. It's also good to listen to feedback of those around you, but the products available at your average store might not be the universal solution you think they are.

Eta: I say, essentially, "everyone has different needs in this area" and the hygiene gestapo show up lmao

No, I played then when I was 13 and I stopped because I grew up.
