If there are any hair loss treatments with good reviews, could you honestly recommend one?

I noticed my hair loss was gradually progressing, so I visited Maypure Dermatology and a few other places nearby for consultations. However, the types of hair loss treatments are more complex than I thought, and the quoted prices vary widely, so I returned home hesitant to make a payment. They said I get a discount if I pay in units of 10 sessions, but I wasn't convinced that hair loss treatments costing millions of won were worth it.

How noticeable were the actual effects you experienced when you consistently received hair loss treatments, such as injections or radiofrequency lasers, session by session? I often see reviews saying they spent money but saw little effect, so I’m being extra cautious. Haha. If there is a hair loss treatment that you feel was truly worth the money, could you honestly recommend it?
