Kenalog injection for hypertrophic scar after facial fat transfer, how soon do I have to wait between?

I have a hypertrophic scar on my face. I had 2 treatment of kenalog and v beam lasers and was seeing improvement. the kenalog really made my scar flatten down. 2 weeks ago I had face fat transfer and dr suggested put a little Nanofat/prp into the raised scar as well coz it helps the texture in long run. My question is how soon after this can I have kenalog/laser again, I don’t want to interrupt the Nanofat but I also want it to be as flat as possible asap so it can be covered by makeup.
