Details: Should you go to Konikoni City, you will find a salonist on a bench near the lighthouse who is looking for a Pokemon with long blonde hair. If you show her an Alolan Dugtrio, she will thank you by giving you a Dire Hit, leaving for her own after she does. Should you return to her another time, she will actually be back with an Alolan Dugtrio of her own. However, this Pokemon won't react to her. If you return with Honey Blonde Hair, it will start reacting to you. The salonist will realize this, thank you with some Soft Sand.
