You still have hair and if you are happy with, that is what counts. As you can style it now and mostly cover it, you will have to decide if you want to take matters into your own hands before it becomes mo obvious or wait. I was in the take action before it was noticeable group, but many here waited. There is no correct answer that fits all.
I might wait until I get a few weeks holiday from work, shave it off, see if it looks good, and if it doesn't it will at least be a little grown back by the time people see me.
