Is it rude to go to the hairdresser with dirty hair?
General rule of thumb: come with clean(ish) hair. This doesnt necessarily mean freshly washed hair (2-3 days from your last shampoo is generally fine). But hair that is overly dirty, greasy or even just full of product makes it harder for hairdressers to get to know your hair in its natural state.
How much should you tip your hairdresser 2021?
The bottom line: If you like your hairstylist, tip at least 20%. It helps build relations with the salon and is especially helpful in procuring a last-minute appointment. Says Camoro: You want to get the best personal care, and build up a rapport.
