Histogen is science-fiction? That doesn't make sense at all since they're quite real and have produced results.
We were nowhere near the amount of knowledge we have today 15 years ago. 15 years ago, virtually scarless FUE megasessions were just a dream.
Today, you can get into a surgeon's office as a NW5, get 3000 grafts for 7000€, which can make a tremendous difference compared to being slick bald.
Today, we have temporary SMP which can be a good addition to a FUE megasession. We can transplant beard hair. Histogen and Replicel are only a few years away.
Other medications are currently being tested. People who say hair loss solutions haven't progressed since the year 2000 are quite delusional.
Of course we had improwments since 2000, we had dutasteride, fue and smp but we are not going to have anything which can give us full head of hair during our life spam, and whoever thinks or hope other way is delusional
