How people wash hair in the old days without shampoo?
Liquid shampoo was invented by Hans Schwarzkopf in 1927. So humans have only been using shampoo for only 94 years!
Shampoo in those days were created for the purposes of cleaning and removing the dirt and oil from hair only. It was not adapted to the characteristics of hair or scalp. With that, the shampoos at that time may not be the best choice for scalp and hair health. Rather, it often cause hair dry and frizzy.
