This fancy mascara/”hair food,” first manufactured in 1912, was mostly made of petrolatum, a kind of vaseline, hence the suffix “een,” according to The Trade-Mark Reporter (1921). The Maybell Company of Chicago - which later become Maybelline - put out an imitation of Lashneen called Lash-Brow-Ine or Lashbrow. Lashbrow came two versions, Natural Growth and Dark Growth. The latter was a mixture of charcoal and vaseline. See here for more of the history of the Maybell Company, and more advertisements.
