Tricks to make your curls more defined are to keep your locks moisturized and apply styling products while it's wet. You can use curl-defining creams, mousses, or gels, depending on your preference. When you’re putting them in, section your hair so you get good coverage, and use a scrunching motion, or gently run through with your fingers, depending on the type of curls you have. Once you have the product in, try to avoid messing with it, either letting it air dry or gently diffusing. Lastly, an excellent cut can also help define your curls by removing excess weight.
