What type of product is typically used to define curls?

Hair gel is a product specifically designed to help define curls and provide hold. It contains a higher level of hold agents that can help to enhance the definition and structure of curls, making them appear more defined and less frizzy. The formula typically offers a firm consistency that allows curls to maintain their shape throughout the day.

Leave-in conditioner primarily serves to hydrate and detangle hair rather than provide the necessary hold for curl definition. Hair mousse adds volume and can also offer some light hold, but it may not be as effective as gel for achieving highly defined curls. Styling cream focuses on texture and softness, which might help with frizz control but does not provide the same level of hold needed to keep curls defined.

Using hair gel is a common technique among individuals looking for long-lasting curls, as it allows for styling versatility while maintaining curl integrity throughout various activities and weather conditions.
