That's what gets me. Every professional person spends a lot of time on their hair. Natural curls and a good cut would take far less time than dealing with my long, thick straight hair with its cowlicks.
And they just ignore altogether the biggest uproar over grooming standards in the memory of any living person. And that was the long hair, hippy influence of the sixties which caused much contention in most K-12 schools and in many business settings for at least a decade.
