What is an indication of a successful perm?

The indication of a successful perm is that the hair shows elasticity after the processed curl is set. This characteristic is essential because elasticity means that the hair can stretch and return to its original shape without breaking. When a perm is successful, the curls should hold their form while still allowing the hair to bounce back, demonstrating that the hair structure has been effectively altered by the perm solution.

In contrast, frizziness and dryness indicate that the hair may have been damaged during the perming process or that the curl formation did not achieve the desired outcome. These conditions can compromise the overall appearance and health of the hair. Additionally, fading hair color can suggest that the perm chemicals interacted negatively with any existing hair color, which is not a sign of a successful perm.

Thus, the ability of the hair to demonstrate elasticity after the curling process is the key indicator that the perm has been effectively executed and that the hair has retained its health and vitality.
