Which perm generally does not require curl creams, pomade or gels to achieve curl?

• A. The heat perm
• B. The cold perm
• C. The digital perm
• D. The acid perm

Answer: (A)

The effect of heat in setting curl is the key idea. In a heat perm, heated rods are used during processing, so the hair adopts a curl shape while the heat helps the curling atoms set as it cools. Because the curl is formed and locked in by that heat-activated process, it often holds without needing extra curl-enhancing products like curl creams, pomade, or gels. Other perm methods rely more on the chemical change alone or on post-perm styling to define and maintain the curl, which is why they typically require some product to achieve or keep the desired look.
