Are there various stories regarding reviews of hair loss treatments?

I tried using shampoos and tonics but saw no significant improvement, so I felt it was time to visit a hospital and receive professional hair loss treatment.

I compared many actual treatment reviews from various places to choose a hospital. I gained a lot of confidence after seeing honest reviews from patients stating that their hair roots had strengthened and thinning areas had filled in. I was particularly impressed by the reviews stating that they improve the scalp environment from the root through personalized hair loss treatments, so I wanted to get a consultation here as well.

I am wondering if injection therapies like follicular injections or mesotherapy would be suitable for my M-shaped hair loss, or if methods like hair transplantation or scalp tattooing would be more effective.
