I went to a new barber in town to get a trim and left with red patches on the back of my neck. When he was using a small trimmer on my neck line I could feel some discomfort. When I got home I looked in the mirror and it looks like I have a sunburn where he used the trimmer from the hair line to wear my shirt collar starts. I applied some witch hazel that stung when I was putting it on. Does anyone have any other suggestions to reduce the reddness? Thanks.
