I have been lucky enough to get on Olumiant. I’n five weeks I have a mustache and patches of hair growing. Im 68 and been dealing with my hair growing in a falling out. This drug has some serious side effects that you need to monitor. 
My sense is that alopecia is IS a “systemic disease” process. I have had a bowel resection, mitro valve repair,  of course episodic stomach issues and eye issues, recently retina repair… I.E. everything related to human anatomy and hairlike structures such as peristalsis, and honestly everything dealing with “hairlike structures” inside and out. Just my own opinion.
