Hi, I am on 20th day after my 4000 grafts FUE Pen method Hair Transplant and little bit of shedding has been observed. I can see lot of my grafts are not grown fully, like they seems thin even if my donor grafts were healthy. In some multiple follicle grafts, I can see only single hairs are growing fast. Is this expected? Do these grafts will grow with its expected thickness and density after shedding phase? There will be any major difference in thickness comparing this 20th day and let's say after 5-6 months?
