In summary: He stopped washing his hair with any products and started using just cold water, in an effort to help with his dandruff problem. Overall seems to have worked for him. Seemed mildly interesting to me.
Not actually NSFW, but I tagged it because the thumbnail is a close-up of some pretty severe dandruff, and there’s a few seconds of video in the middle where he shows the condition of his scalp before quitting shampoo. Just thought I’d mention, in case that makes you squeamish.
We’re interpreting this comment very differently. The way I read it, they’re saying that the oils and microbes that occur naturally on our skin are largely beneficial to good health, which means that there are downsides to removing it.
That shouldn’t be controversial. It’s not saying “never wash”, but rather pointing out that excessive cleaning with soap can negatively impact your health. There’s plenty of evidence that that’s the case.
Of course, you should be washing your hands properly, there’s also plenty of evidence that not doing so causes disease. I think the major point here is that it’s not black and white. Excessively washing your whole body with soap can very well lead to dry/cracked skin and skin infections.
