This is for those who have noticed facial changes after taking Propecia. I don’t think it’s easy to tell notice these changes in photos. A CT scan however will be a lot more conclusive.
This is what bone waste looks like on a CT scan:
When you age, the bone recedes a particular way. It’s how archaeologists and crime scene detectives can differentiate between a young and old persons skull.
My suggestion is that those of you who claim to have facial changes get yourselves a CT scan. If you have suffered accelerated recession of features in the skull, it will be evident. You could even get an independent expert to estimate how old you are based on the images.
