Wigs are a very specialized industry. I had a friend whos husband immigrated to Canada via Express entry being a wig maker specializing in natural, hair based wigs, that’s how high in demand the profession is. The guy was supplying multiple province’s patients with wigs.
I’d imagine that such a business would not have to stay open for long hours during the day or even multiple days per week due to most orders actually coming in through phone from healthcare providers or those affected.
Where I live, we have a helium balloon party store nearby. It’s open two hours a day from 10:00-noon, except on Saturday it’s 10:00-13:00. The guy’s business is booming, you can see people lining up for their orders and picking them up during that window. The store is so specialized but affordable compared to their big box competitors like party city etc, it’s hard to beat.
