In twenty years of solo adult visits to the hairdresser not a single one recognised I have curly hair (~2b, clearly wavy when wet) which to me is the biggest hair crime, not actually understanding the material you are working with every single day.

One even permed my hair several times and was shocked how quickly it took a curl! Another gave me a lovely layered cut that would 'work with my slight waves', looked like Farrah Fawcett by the time I'd walked five minutes across town.
