It couldn’t be simpler. If your clients are happy, they’ll come back. If your clients are happy, they’ll tell their friends. You’ll keep the clients you have. You’ll get new clients. And (cue celestial chorus here)—you’ll make more money. So when the rent’s due, you won’t have to get an advance on your birthday money. You’ll be able to replace that bashed-up back bumper on your Prius. And that trip to Cabo that’s on your bucket list? Start packing Señorita!  So how do you keep your clients happy? L.A. Hair’s Jonathan Antin lays it out for us.
