There will be a change in your appearance regardless of how minimal or expansive.
There may be a reaction - not necessarily with words. Either you brush it off or not. Just be prepared.
In my experience, it was minimal. One person thought I had had a transplant - that was a few years after I started wearing and at the time of first wearing, a flatmate - women seems to be more observant - noticed a change, but could never quite work it out. I said, a new hairstyle and exercise. Everybody else either didnt notice or didnt care.
