Messy French braid is tied by starting it with a front of your head. After that grad an each section from the sides. And also a grad from middle to braid them just like a regular French braid. The braid section looks and is picked to the closest section that make it look neat. But, make sure to pick a little more spaced out that is thinner than the strands over the head. So that your head reaches to the nape of your neck, that can either fishtail your braid or normal it. You can just braid it regularly that if you have the time and the hair length to look beautiful.
