Which perm creates tighter, more defined curls?

A traditional perm using smaller rods is the correct choice for creating tighter, more defined curls. This method involves wrapping the hair around rods that are smaller in diameter, which allows for a more compact curl formation. The smaller the rod, the tighter the curl will be due to the increased curvature that the hair takes as it wraps around. This process typically involves the use of a chemical solution to break down the hair’s internal structure, allowing it to take on the new shape defined by the rod size.

In contrast, a digital perm, which utilizes heat, typically results in softer, more natural-looking waves rather than tightly defined curls. A body wave perm employs larger rods, which also leads to looser curls or waves rather than the definition required for tight curls. Lastly, a relaxer treatment is designed to straighten curly or wavy hair, which is fundamentally opposite to creating curls. Thus, the traditional perm with smaller rods is the optimal choice for achieving tight, well-defined curls.
