For short hair or for someone who wants it styled, I'd agree that curly hair should be dry when cut.
I'm not PP but I'm a dude with long, curly hair and I just want an even trim, so it's much better if my hair is wet.
(Also, shampoo is harder on curly hair than straight hair; "wash" curly hair with water every day and use some conditioner, and only use shampoo if it feels dirty. That may only be once week or two, maybe once a month if the hair is short. Yes, really.)
