I recently came across a Threads post from @idea.soup that said: “I don’t have any evidence for it but I have a weird feeling the anti-polyester movement is about to become a right-wing pipeline” This was a lightbulb moment for me! I started doing scicomm in 2011 because I realised the “non-toxic” clean beauty movement could be a pipeline to …

Here’s the problem: Most scalp products aren’t treating the right cause, and no one’s really explaining what that is. And a lot of scalp products actually make things worse.

I’ve become a bit of an airborne transmission nerd during the pandemic. Every once in a while I’ll share some of the tools I use on social media, and I’ve realised quite a lot of other people are also interested in how to not get sick, or at least get sick less, outside of getting vaccinated.
