The hair transplant failed... It's really bitter

I was very excited and stressed for 8 months.. Looking at my head after 8 months, it's just heartbreaking and annoying because the waiting time seems to be in vain..
You can count the number of hairs in the area where the hair transplant was done. It just looks like it was before the hair transplant when you look under the lights
I did 2500 mo, but 2500 mo is not a lot of mo....?
I haven't been to the hospital in less than a year, but in 6 months, the doctor told me that if the density seemed a little low, he'd give me a retouch.. When are you sitting there waiting for that... ahem... Anyway, I'm just annoyed, so I complained like this
