Changing your hair color on Snapchat can be a great way to show off your personality and have some fun with the app. To get started, open up the Snapchat app and take a selfie or upload one from your camera roll. Once you've selected the photo, tap on it to bring up the editing tools at the bottom of the screen. You'll see an icon that looks like a brush — this is where you can start changing your hair color! Tap on this icon and select either Hair Color or Highlight, depending on which shade you'd like to apply. From there, pick any shade from the wide range of colors available in both categories. You can also adjust how much of each shade appears by dragging left or right along its slider bar. Once you're happy with your new look, hit save and share it with all of your friends!
