How much did shampoo cost in the 1920?

In the 1920s, the cost of shampoo varied but was generally around 25 to 50 cents per bottle, depending on the brand and size. This was a time when commercial shampoos were becoming more widely available, moving away from homemade soap solutions. Adjusted for inflation, this would be equivalent to several dollars today. The rise in popularity of personal hygiene products during this era reflected changing societal norms around grooming and cleanliness.
