I had a similar experience getting a beard to scalp transplant a few years back. The procedure itself wasn't too bad, but I did experience some discomfort and swelling for a few days afterwards. It took a few months for the transplanted hair to start growing in, but once it did, I was really happy with the results.
In terms of cost, I paid around $5000 for the procedure and had it done at a reputable clinic in my area. Overall, I would say it was worth it, but just be prepared for some downtime and potential side effects. Make sure to do your research and find a skilled surgeon who specializes in this type of transplant. Good luck with your journey!
