Is it possible to proceed with the hair loss treatment immediately after the consultation on the same day?

Hello! Since my workplace is near Gangnam Station, I am planning to visit the Maypure Gangnam branch for scalp care, as it is convenient to visit after work. My hair has been thinning recently, so I would like to receive professional hair loss treatment.

I would like to know if it is possible to visit without an appointment on a weekday evening after work and complete the hair loss treatment all on the same day. I want to check in advance if there might be a long waiting time during rush hour so that I can make a reservation.

I would also be very grateful if you could let me verify the genuine ampoules used during the procedure at the Gangnam branch in front of me, and provide guidance on precautions such as whether I can shampoo or wear a hat on the day of the hair loss treatment.
