In the last half of the 19th century, barbers filled
their own bottles with hair tonic, hair oil, bay rum, shampoo, and
rosewater. The bottles came in distintive colors/shapes so they barber
could identify what was in each one of them.
Most of them have gold trim around the top of the bottle.
These bottles stopped being made after the 1906 Pure Food and Drug Act made
it illegal to refill non-labeled bottles.
