@BlueRevolution Correct! Hair care as we know it wasn't around prior to 1890 give or take!
Prior to that, people used to only care about preventing parasites. We used a lot of talc based powder, spit based pomades, and various other things that didn't even really prevent parasites either.
People also used to lose their hair from syphilis and wear a lot of wigs to cover balding.
Doctors also used to leach out the "bad blood" to "cure" people.
Would you still use that medicine?
