Certainly could if it had good contact. If it was air gapped (held up by hair), it could be an effective barrier for shorter wavelengths.

I took some antenna theory courses back in the day and yes, you are correct. Some frequencies reflect off the upper atmosphere so there would be a longer effective range at higher incident angles (going into the top of the head) but it wouldn’t completely block radio waves. Going from memory, the wavelengths that reflect off the upper atmosphere are long enough that a tin foil hat wouldn’t cause much interference anyways.
TLDR: Fashionable, but not practical.
Yay! We get to rename the drink “Irish Car Bomb” to “MAGA Tantrum”. At least something good came out of all this.
Honestly, for how much fresh water they hold, I’m surprised how small their watershed is.
