I wouldn't let your g'freind anywhere near it. Surely it's impossible to skin fade if never done before? I wouldn't worry, the barbers will be open in 3-4 months 😂
Doesnt look that hard in the videos I have watched. The actual cutting of it she wont be doing, but the actual fade, while it wont be amazing, is going to be better than having 2 inch long hair there.
