Perm Hairstyle Test! Trivia Facts Quiz

The size of the curl depends on the rod size used during the perming process. Different rod sizes create different curl sizes, with larger rods resulting in looser curls and smaller rods creating tighter curls. The rod size determines the amount of hair that is wrapped around it, which directly affects the size and shape of the curl. Therefore, choosing the appropriate rod size is crucial in achieving the desired curl outcome.

Twisting or stretching a rubber too tight can cause it to reach its breaking point and result in breakage. When a rubber is subjected to excessive force or pressure, it may exceed its elastic limit and snap, leading to breakage. This can happen due to the material's inability to withstand the applied stress, resulting in a loss of structural integrity and ultimately causing breakage.

The perm wave lotion to be used is determined by the condition of the hair because different hair types require different levels of strength and treatment. For example, if the hair is damaged or weak, a milder lotion would be used to minimize further damage. On the other hand, if the hair is healthy and strong, a stronger lotion can be used to achieve the desired results. Therefore, considering the condition of the hair is crucial in selecting the appropriate perm wave lotion.

Elasticity tests the internal strength of the hair by measuring its ability to stretch and return to its original shape without breaking. This is an important factor in determining the overall health and condition of the hair. Hair with good elasticity is more resistant to damage and breakage, while hair with poor elasticity is more prone to breakage and can indicate underlying issues such as dryness or damage. Therefore, elasticity is a key indicator of the internal strength and health of the hair.

Perm lotion has a softening action on the hair. This means that when the lotion is applied to the hair during a perm treatment, it helps to relax and loosen the hair's natural texture, making it more pliable and easier to manipulate. This allows the hair to be curled or styled into the desired shape during the perm process.

The 'S' bend determines that development is taking place. This suggests that the 'S' bend is a visual indicator or a sign of progress or growth in a particular context. It could be referring to the development of a project, a system, a product, or any other aspect where progress and advancement are being observed.

Porosity refers to the hair's ability to absorb and retain moisture. It measures how easily water and other substances can penetrate the hair shaft. The more porous the hair, the more it absorbs water. Therefore, porosity tests the hair's ability to absorb moisture, not its external strength. External strength of the hair refers to its resistance to breakage and damage from external factors such as heat, chemicals, and styling.

The correct answer is "the condition the hair will be in after the perm." This answer suggests that the purpose of the pre-perm test curl tests is to assess the condition of the hair after the perm has been applied. It helps determine if the hair has been properly treated and if the perm has achieved the desired result.

A perm lotion with a pH above 9.5 is highly alkaline. Alkaline substances have the ability to break down the protein structure of hair, which can lead to hair removal. Therefore, a perm lotion with a pH above 9.5 may act as a hair remover.

Peptide bonds are the chemical bonds broken down by the perm. These bonds are formed between amino acids in a protein chain, and they are responsible for holding the chain together. During a perm, the chemicals used break down these peptide bonds, allowing the hair to be reshaped and curled.
