How do these companies come to that conclusion? I think most people start to smell after only 24 or 48 hours max so how do these companies get 72 hours out of their testing?

Im assuming they’re fudging their numbers but at what point does it become false advertisement?

      I don’t know how they measure it, but I used to stink despite showering twice a day. I had to put a lot perfume and deo. I always had the feeling that my bath towels were stinking. Until, one day I ran out of soap and used my head and shoulder as soap and also forgot to put deo. 24 hours later there were very litle sent that you had to be mm away from under arm to smell anything. Now I just use head and shoulders as my soap and shampoo. I only use deo if I’m going to do labour intensive movements/activities. My wife was shocked when I told her I havent used deo in over 6 months. Her only concerns is about safety, since I am using it daily. If any of you reading this are scientists let me know the risk of the daily usage.

        Head & Shoulders contains ingredients that have anti-fungal properties: 

Zinc pyrithione
Also known as ZPT, this ingredient is an active ingredient in Head & Shoulders dandruff detox shampoo. It can reduce the amount of fungus on the scalp, which can help prevent dandruff. ZPT can also help manage seborrheic dermatitis, an inflammatory scalp condition. However, it can cause contact dermatitis in rare cases. 

Selenium sulfide
This ingredient acts as an antifungal and antibacterial cleansing agent. It can help prevent the growth of Malassezia, a type of yeast that causes dandruff. However, it can cause excessive oiliness and yellow discoloration in the hair shaft.

        I think you had fungal infection mate

        Why would it be wrong to use daily? Many people shower daily and use it as shampoo.

        Why not go talk to your doctor and see if you have a fungal skin infection. Many of them are nearly undetectable. The doctor should be able to give you an antifungal pill to take for a few weeks and you should be smelling normal again.

        I periodically used mouthwash, on my arm pits, as a teenager. It cleared the funky smell quite impressively. I would definitely suspect head and shoulders anti fungal properties as the useful bit.

        i’m very convinced it makes you stink worse than it otherwise would when it expires.

          Not at all, now I shower only one time a day with no deo, and if I feel my armpit is swaety i just rinse it with plain water until I shower. No funcky smell at all. Even sex sweat is not funky anymore.
