Women are often charged more than men for haircuts performed by the same hairdresser. This is not considered price discrimination because:

Women receive more consumer surplus from haircuts than men.

Hairdressers claim to spend more time on women's hair, which raises the cost of haircuts for the company.

Companies offset the additional cost to consumers by giving women free product samples.

Men receive more consumer surplus from haircuts than women.

Women have a lower price elasticity of demand for haircuts.
