    The ability of hair to absorb moisture

    • Elasticity

    • Strength

    • Thickness

    • Porosity

    Correct Answer
    A. Porosity
    Explanation
    Porosity refers to the ability of hair to absorb moisture. It is a measure of how easily hair can retain and absorb water or other substances. Hair with high porosity tends to absorb moisture quickly and easily, while hair with low porosity is more resistant to moisture absorption. The porosity of hair is influenced by its structure and condition, such as the cuticle layer and damage from chemical treatments or heat styling. Understanding the porosity of hair is important for choosing the right hair care products and treatments to maintain its moisture balance and overall health.

    The correct answer is the match test. This test involves taking a small strand of hair from the wig and holding a flame to it. If the hair burns and turns to ash, it is human hair. If it melts and gives off a plastic smell, it is synthetic hair. This test is effective in distinguishing between human hair wigs and synthetic hair wigs.

    The human hair that is considered top of the line for hair wigs is

    • Indian hair

    • Asain hair

    • Virgin european hair

    • Dominican hair

    Correct Answer
    A. Virgin european hair
    Explanation
    Virgin European hair is considered top of the line for hair wigs because it is known for its high quality and natural appearance. European hair tends to have a finer texture and is less prone to tangling and frizzing compared to other types of hair. Additionally, virgin hair refers to hair that has not been chemically processed or treated, making it the most desirable for wig making as it can be easily styled and dyed to match different preferences.

    The changes that take place in the hair during permanent waving, chemical relaxing, and oxidation hair coloring occur in the

    • Medulla

    • Roots

    • Cuticle

    • Cortex

    Correct Answer
    A. Cortex
    Explanation
    The changes that occur during permanent waving, chemical relaxing, and oxidation hair coloring happen in the cortex. The cortex is the middle layer of the hair shaft and contains the pigment that gives hair its color. It is also responsible for the hair's strength, elasticity, and texture. During these chemical processes, the cortex is altered to change the hair's shape, texture, or color. The medulla, roots, and cuticle do not play a significant role in these changes.

    The chemical bonds that join amino acids to each other are called

    • Peptide bonds

    • Side bonds

    • Hydrogen bonds

    • Salt bonds

    Correct Answer
    A. Peptide bonds
    Explanation
    Peptide bonds are the chemical bonds that join amino acids to each other in a protein chain. They form through a condensation reaction between the carboxyl group of one amino acid and the amino group of another. This process releases a molecule of water and creates a strong covalent bond between the two amino acids. Peptide bonds are essential for the formation and stability of proteins, as they determine the primary structure of the protein chain. Side bonds, hydrogen bonds, and salt bonds are not specifically involved in joining amino acids together.

    The amount of movement in the hair strand is referred to as its

    • Wave pattern

    • Density

    • Texture

    • Porosity

    Correct Answer
    A. Wave pattern
    Explanation
    The correct answer is wave pattern because the amount of movement in a hair strand refers to the pattern of waves it has. Wave pattern describes the shape and direction of the waves in the hair, such as straight, wavy, curly, or kinky. Density refers to the thickness or thinness of the hair strands, texture refers to the overall feel and structure of the hair, and porosity refers to the hair's ability to absorb and retain moisture. None of these options specifically describe the amount of movement in the hair strand, making wave pattern the most appropriate answer.
