Red Head? How long will my head look like a bleeding pin cussion afte my transplant ?

[Topview]

Getting a transplant in January and looking for some feedback as to how long my head will be red/scabby / bleeding and I guess not look like I just had 5000+ hairs transplanted

Is it okay to wear a hat to the office or should my head be able to breathe? I will be getting it done on a Thursday and taking the entire following week off as well.

Thanks in advance
