What type of roller curl creates maximum closeness or indentation?

The type of roller curl that creates maximum closeness or indentation is the full under directed curl. This technique involves placing the roller directly under the hair section, which results in the hair being wrapped around the roller completely. The under-direction causes the hair to curl tightly around the roller, creating a strong, defined curl and significant indentation.

Using full under directed curls is particularly beneficial when aiming for a more structured look or when a style requires great hold and definition. This method contrasts with other curling techniques that may result in softer, more relaxed curls without as much indentation. The way the hair is wound around the roller has a direct impact on the overall finish and definition of the curl created.
