I'm curious about the price of hair loss treatment.

Lately, whenever I tie my hair up, it bothers me because the crown of my head looks thinner than before. It feels even more noticeable in photos, so I am considering looking into hair loss treatments. However, after searching online, I found that prices vary by clinic and there are many different treatment methods, so it is difficult to decide which one to choose....

For those of you who have received hair loss treatments, which procedure did you choose? I am curious whether it was actually effective and how many sessions were required to see changes. In particular, I would like to know if hair loss treatment is a one-time procedure or if it needs to be continued at regular intervals. Since the cost of hair loss treatments seems to vary more than I expected, I am wondering what a reasonable price range is.

If anyone has tried this treatment personally, please share an honest review covering the treatment time, recommended sessions, and satisfaction level.
