I Have Alopecia Areata with Multiple Spots on My Face That Come and Go with Treatment.

Alopecia areata is not always curable. It can come and go with treatment, stopping while being treated and then returning as you seem to disclose.  This is not atypical for this disease, and it is something that you may have to learn to live with. The beard area can be treated very nicely with scalp micropigmentation.
