I had a FUE procedure almost a year ago and noticed these small bumps on the hairline. If this is Cobblestoning? If so, what caused this and what can be done to repair this? I have my 1 year follow up coming up with the surgeon and was wanting to go over a 2nd procedure for more density but if this is a surgeon error I would like to know so that I don't go through with a 2nd surgery with this surgeon. Thanks in advance!!
