Inquiry about hair loss treatment

Hello. I am an office worker who is deeply concerned because recently, the amount of hair I am losing is not what it used to be, and my scalp, especially on the crown of my head, seems to be clearly visible. I have tried changing my shampoo and taking supplements on my own, but I haven't seen much effect, so I have finally decided to seek professional hair loss treatment and am writing this inquiry.

I searched online, but there are so many different types that I am at a loss as to which direction to proceed. My specific questions are as follows:

Treatment Types and Duration: Due to my busy schedule, it is difficult to take a long time to visit the clinic. I would like to know what the representative hair loss treatments are mainly recommended by the clinic, and approximately how long each session takes, including anesthesia and preparation.

Recommended Frequency and Cycle: I have heard that consistent care is key to managing hair loss. I would like to know how many hair loss treatments are typically required to see noticeable results, and whether the treatment intervals are weekly or monthly.

Effectiveness and Duration: I am also curious about the average level of satisfaction one can expect regarding strengthening existing hair or promoting new growth.

I would like to have my current scalp condition accurately diagnosed and receive a personalized consultation. I would also appreciate it if you could provide an overview of the initial consultation process and costs. I look forward to your reply. Thank you!
