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?

    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.
