During the shampoo procedure, it is important to monitor the water temperature. This is because using water that is too hot can cause discomfort and damage to the scalp, while water that is too cold may not effectively remove dirt and oils. By monitoring the water temperature, the stylist can ensure that it is at an appropriate level for a comfortable and effective shampooing experience.

Wiry/Curly hair type is very resistant to hair pressing and requires more heat and pressure. This is because the natural texture of wiry/curly hair is tightly coiled, making it more difficult to straighten. The tight coils create more resistance to heat and pressure, requiring higher temperatures and more force to effectively straighten the hair.

The water-attracting head of the surfactant molecule is called hydrophilic. This term refers to the property of a substance to have an affinity for water, allowing it to easily mix and dissolve in water. In the context of surfactants, the hydrophilic head is responsible for attracting and interacting with water molecules, while the hydrophobic tail repels water and interacts with nonpolar substances. This property is crucial for surfactants to function effectively in various applications such as cleaning, emulsifying, and reducing surface tension.

High-pH Shampoo is the correct answer because it can leave the hair dry and brittle and cause fading in color-treated hair. Shampoos with a high pH level have a higher alkaline content, which can strip away the natural oils and moisture from the hair, leading to dryness and brittleness. Additionally, the high pH level can also cause the color molecules in color-treated hair to fade more quickly. Therefore, using a high-pH shampoo is not recommended for those with color-treated hair as it can have negative effects on both the hair's condition and color.

The pH scale is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most alkaline. This scale is logarithmic, meaning that each whole number change represents a tenfold difference in acidity or alkalinity. Therefore, a solution with a pH of 2 is ten times more acidic than a solution with a pH of 3. The range of 0 to 14 encompasses the entire spectrum of acidity and alkalinity that can be measured on the pH scale.

Normalizing Solution is the correct answer because it refers to conditioners with an acidic pH that help to restore the natural pH of the hair after a relaxer treatment but before shampooing. These solutions help to balance the pH level of the hair, which can become alkaline after a relaxer. By restoring the natural pH, normalizing solutions help to close the cuticles of the hair, making it smoother and more manageable.

Shaping is the correct answer because when preparing for the formation of a pin curl, a section of hair is molded in circular movements. This shaping technique helps to create the desired shape and structure for the pin curl. Curling refers to the process of creating curls in the hair using various tools, while waving refers to creating waves. Perming involves chemically altering the hair's structure to create permanent curls or waves, which is not the same as shaping for a pin curl.

Brushing the hair after a chemical service can cause damage and breakage to the hair. Chemical services such as coloring, perming, or relaxing can weaken the hair's structure, making it more prone to breakage. It is recommended to wait until the hair has fully recovered from the chemical treatment before brushing it to avoid further damage.
