If anyone can help :)

I am driving myself crazier than I already am trying to figure out this bottle!

Does anyone have any idea what it could be?

4" tall
11 inside of a hexagon on the bottom as the marking. No letters or anything else.

That’s Halo shampoo from around 1950’s

I find ads from as early as 1890 all the way to 2015. Believe it or not the bottle looks about the same from day one to now.
Fist an ad from the 1930's and one from 2015.
