I did it in November 2017, and after about 3 months, the scar almost disappeared, and now after about 6 months, only a white line remains. Fortunately, it's all covered by my hair!!><
I used to have an M-shaped hairline, but now... it's just a square forehead. It's still wide. It was 7cm, but I think it decreased by about 1cm. They said they would decrease it by 1.5cm in the middle and 2.3cm at the corners, but it feels like it was about 1cm... But I'm still satisfied.
I can walk around without bangs. I'm happy that my feeling has returned~ I'm so satisfied. I'm planning to get a tattoo on the scar area and get hair grafts later^^
