When can we put oil on our recipient area? Thank you!!

I am currently 20 days post op from an FUE transplant for my frontal hairline. I have been using emu oil on my donor area from the start and have great results. My recipient are is healing well but I just want to give it a little extra with emu oil or coconut oil. My question is, when can I put oil on the recipient are? Is it safe? Will it harm grafts? Is there even a point in putting oil in the recipient are right now? My scabs are also gone, i just have a little bit of pink in some areas
