I've always had fine blonde hair. I was a Norwood VI in 2012 and had over 5,000 grafts transplanted in a mega-session. I've never taken any meds prior to or post surgery for hair retention. My wife is a hair dresser and cuts my hair regularly and sees no discernible hair loss over the past 10 years in the recipient areas. I've posted pictures and narratives for the past 10 years at the site below (over 380,000 views). Best of luck to you!
