I made a reservation through Naver and went, but this month was very fully booked. I think it would be better to check in advance and make a reservation. I asked if I could get an appointment earlier than my reservation time, and they said it was okay even if there was a wait, so I went and it was done faster than I thought. The hospital was clean and the staff were friendly. The doctor asked me in particular which areas I wanted to be treated with extra care and did a great job!! I definitely think Gentle Max is effective. I could feel my hair getting thinner right away. I think it would be even more effective if I get it consistently. It hurts more than Apogee, but Gentle Max is definitely more effective. If you're worried, I think it's better to pay extra and get Gentle Max unconditionally. I feel like having done Apogee 5 times is equivalent to having done Gentle once.
