adding streaks with a gradient effect

When the contrast between two colours is strong and you want to soften it you can add streaks and gradually space them out more to give a slight gradient effect. This works well for when you’ve done a colourful bangs/fringe replacement and you don’t want it to look punk/goth but more integrated into the overall hairstyle. In this case since it’s a reroot I could have done a blend to ease the transition but I hadn’t got a plan in mind ¯\_(?)_/¯
