Is the cost and pain of a hair transplant surgery for early-stage M-shaped hair loss severe?

Hello, I am a male office worker.

I am stressed because I can see my hairline receding and my hair thinning in the M-shaped areas on both sides of my forehead. I have been taking hair loss medication for a few months, but it seems that the medication alone is not restoring the M-shaped areas that have already receded.

I am considering a hair transplant for the M-shaped hairline, and I would like to know about the pain and recovery period if I proceed with the non-incisional method. Since I have to go to work, I am worried that swelling or redness might be very noticeable during the graft engraftment period. I would also like to know how many grafts are typically implanted for M-shaped correction, and hear about the engraftment rates and post-operative reviews from those who have actually undergone the surgery.
