10 months post-op, male, age 22, 3360 grafts - has my hair transplant failed? (Photos)

I (22M) had a hair transplant 10 months ago with 3360 grafts on my frontal area. The progress was slow for the first few months with alot of itching and folliculitis. Now 10 months later the result is no where near what I expected. The transplanted hair falls regularly and the hair density is very less. I have been taking finasteride and monoxide 5% spray once at night. I have also been taking multivitamin and biotic tablets. What can I do to accelerate hair growth and get hair density right?
