I wanna revive this old thread...LOL.
The cotton on hair...if you've ever seen Our Gang w/ Farina or Buckwheat, that's what it looked like, was indeed a protective style. The hair was braided and tied up w/ the cloths around it to protect it. It was commonly done on kids to encourage hair growth. My grandmother, who is 83, says it was pretty much limited to kids and despite how it looked, it worked. So let this be proof that cotton on hair ISN'T the debil! LOL
Back in those days, almost everything was "all purpose". Pine products (aka known as "carbolic") were used very commonly for both animals and people as well as building materials, cleaning agents (turpentine) etc. IOW, pine products were the "Dr. Bronner's soap" of it's era. It's still around, but you'll have to look hard for it.
As for "grease" almost everybody used it...Black, Whites, Asians, etc....even now if you look in almost any grocery store that sells hair products, you'll see White people's grease. Vo5 and Byrlcreem in tubes and a few other tonics are still in common use and sell today. back then, people used whatever grease was available....butter, lard, lanolin, vaseline, cooking fat (read bacon grease), etc.....these folks were the original "green" people. Tho crude, everything sustainable..use it all, waste nothing. LOL...in these days, it's good to learn this stuff in case we need it.
