Just how hairy was the person who invented a shampoo called Head & Shoulders?

I like to imagine the person who originated Head & Shoulders shampoo had really, really hairy shoulders.

Why is there Head & Shoulders shampoo. Who has hair on their shoulders. Whose shampooing their shoulder hair. Please come forward.

TIL that my Head & Shoulders shampoo's proven HydraZinc formula fights dandruff from the first wash, removing visible flakes and residues, relieving dryness and tight scalp, and leaving my hair smelling great. I also learned not to forget my phone when I take a shit
