Final answer:
Curlformers (D) are the correct answer for elongating and styling natural frizzy hair without using heat or chemicals. They create temporary or permanent waves by bending the hair and letting it set, which is a safer method compared to perms or heat styling.
Step-by-step explanation:
The correct answer to the student's question is D) Curlformers. Curlformers are designed to gently elongate and style the hair into smooth, silky curls, waves, and even zigzag patterns. This method is suitable for setting either wet or dry hair and is particularly beneficial for natural curly or coily hair textures, as it does not involve heat or chemicals.
Perm rods and curlformers both can be used to set hairstyles, but curlformers are specifically designed to produce the desired effects mentioned in the question. Unlike heat styling tools, which can cause damage through high temperatures, or hair gels, which offer less structure, curlformers provide a safe and effective way to style hair without damaging it. The resulting hairstyle can be either a temporary wave or a permanent hairstyle, depending on the method used.
When it comes to altering hair texture, it's important to understand that both temporary and permanent waves are a consequence of disrupting and reforming the disulfide bonds in the hair strands. However, curlformers work by bending the hair into desired shapes and allowing it to set naturally, which is less damaging compared to applying chemicals for a permanent wave.
