I think your argument is sound. Upon hearing others mention it as well it seems there is a chance this is the case. Let's take a look at FAK inhibitors. Wounds have been made in pigs and they healed with new skin and hairs. It's not like this wound healing process is impossible then. My concern is though it works, it seems results show hair at roughly 50% normal density once regrown. The thing is we want 100% density or near that. What has to be done in order to accomplish this objective? I'm wondering if the amount or concentration of the FAK inhibitor needs to be changed or something needs to be added with it in order for the hair density to be better. Sadly, I have no knowledge of what to do since I am not in the profession. I can only guess.
One thing that can be useful is when these new studies are published that look promising, they should be forwarded to dermatologists and dermatology departments at hospitals, colleges, etc. Believe it or not, I forwarded an article about FAK inhibitors to a dermatology department of a hospital and the doctors (as far as I could tell) had no idea regarding the research. Ultimately, if we can get the information into the right hands perhaps, they will do something with it, hopefully leading to clinical trials. As I tell in many of my posts, I wish the medical world would take hair loss seriously as they did with Covid-19, because if they did, we'd have a cure a lot sooner. Really, they should care because being able to reverse fibrosis/scarring (like in scarred skin) is the key to curing other deadly diseases.
