If you always go to the same place to get your hair did because so-and-so knows how to make you look good, ask them for their phone number or email. They may not be styling at that spot for long.
A lot of people don't realise that many barbers and hair stylists are not necessarily employees of the barbershop or salon they work at — they're independent contractors who are basically renting out a space to lower dem ears. The people that do your 'do can move from place to place quite often, so that's why it's important to ask for deets when you find someone that gives your hair the TLC it's always deserved. It doesn't have to be an awkward, "Hey, can I get your number?" Just ask if they have a card, or if they have a work email or phone number you can reach them at in the event they jump ship and swim to a better clipper (that's a hair and a ship joke). They will probably be more than happy to keep you as part of their client base.
In the future, you can reach out to them directly and see what days and times they're working, or where they're at now if they have moved on. No more driving to the salon and asking "Is Chloe in?" then feeling obligated to go with another stylist because Chloe is gone and you don't want to be rude and just walk out, but the new stylist just doesn't get your oddly thick hair, so it turns out not amazing but still costs you like $US60 ($78) plus tip. (I'm fine. It's fine.) Just find a good groomer, ask for their info, and stick with them.
