If you’re changing your part, it can take some training to get it to stay where you want. It helps to part on the side where your natural part falls. Otherwise, you can part your hair wet, then blowdry it in the direction you want it to sit. You can also use hairpins to keep things in place, especially when the style is new. Finally, styling products will be incredibly helpful, so try using a hairspray or a matte pomade or wax to add texture and hold.
