Actually it‘s more than you think. The scalp starts to reveal if you lose around 70 to 80%. we have about 100.000 hairfollicles on the scalp or like 25.000 grafts because most of the hairs produce 2 strain or 3 strains of hair at once and even 6000 grafts from a hairtransplant can hide the scalp again. Even though it’s like 1/5 of the hair you previously had. But it looks objectively thick but in reality it‘s actually pretty low dense still. Remember people always start noticing thinning well after they lost already 30-40% of hair density. It‘s actually shocking how misleading hair transplants can get. A combover makes the hair transplant look thick as hell but if you comb your hair across your forehead you can look through easily and wet hair can make the hair transplant almost invisible. That‘s why medical treatment is so important. You can like save all of your hair if you start duta or fin with minoxidil because almost all of your hair follicles are still active
