How do you use head start on sonic dash?

In Sonic Dash, the Head Start feature allows you to gain an advantage by starting your run with a speed boost. To use it, simply select the Head Start option before starting a new run, which will consume a certain amount of Red Rings, the game’s premium currency. This gives you a head start over the competition, making it easier to achieve higher scores and collect more rings. Remember to manage your Red Rings wisely for optimal use.
