Outline Day 9 Review + Can I bow my head?

Now there is no pain and my gums often itch.
 They say that the symptom of returning sensation is itchiness. I think they are right.
 I thought the contour sensation would suddenly come back one day, but it comes back slowly day by day. I
 lost weight because I didn't eat well (I lost almost 4 kg...)
 and facial swelling. If someone who doesn't know me sees me, I wouldn't even know I had surgery.
 People I know have swelling at the bottom that looks like they had their wisdom teeth removed, so
 the effect of the cheekbones is clear, but I'm not sure about the chin because the swelling is below.
 Well, it'll go away someday, right?
 
Anyway, I want to wash my hair today. Should I wash it with my head down or sit in the shower?;;;
 If I bow my head, it feels like my face is going to burst, so I feel uncomfortable.
