Gotta love the internet. Found this wounderful story of the company written by the owner (no less) 12 years ago. The company appears to be in operation still to this day:
“Well, the whole story behind the Hair Milk name is that back in 1910 when my great great grandfather came up with the idea for a product that got rid of gray hair, so he and a couple other barbers began to come up with some formulas and they came up with a product that looked like milk... hence the name. However, in the mid 70's they tried to tell my grandfather that he had to pay for a boiler license and hire professional boiler operators and this he didn't want to do, it was ment to remain a family thing only. He shut down production of the hair milk and we just continued to sell products around the world to barber shops and salons at whole sale prices. The original steel vats and all the production equiptment is still upstairs in our building. Did you ever know there used to be a house attatched to where the warehouse is right now?
How do I know all this and more... it's my company... well my family's company... just my father and I run the entire thing now that my grandfather has retired.”
