25 days post op FUE. Can I use betamethasone that I have been prescribed by my regular doctor for my scalp psoriasis? (Photo)

Im 25 days post op FUE. Before my FUE I cleared my scalp psoriasis.Over the last week I have had small plaques come back and itching bad. I emailed the company I had my FUE with and someone in the office said I can resume this medication. Read the leaflet with the betamethasone it said one rare side effect is hair loss an follicular damage.I've read 5 replies here to a similar question. Each reply says yes resume the meds but with different time frames. Is there a clear answer to this question?
