That cold brew setup @hall.alex mentioned really is a game changer for smooth coffee. Just don't steep it too long or it gets kinda bitter, found that out the hard way.

Yeah the kitchen trick thing... my cousin once used mayonnaise as a deep conditioner because she read it online. It made her hair super greasy for days, like it wouldn't wash out... she had to use dish soap to get it all out and then her scalp was a mess. Sometimes those ideas just don't translate from the internet to your actual bathroom.
