    Extremely curly hair may often break or knot easily due to:

    • Humidity

    • Density

    • High elasiticity

    • Low elasticity

    Correct Answer
    A. Low elasticity
    Explanation
    Extremely curly hair may often break or knot easily due to its low elasticity. Low elasticity means that the hair has difficulty stretching and returning to its original shape, making it more prone to breakage and tangling. This lack of flexibility in the hair strands can be caused by various factors such as heat damage, chemical treatments, or genetic factors. Therefore, low elasticity is a common reason for the fragility and difficulty in managing extremely curly hair.

    Hair texture is classified as:

    • Coarse, medium, or fine

    • Coarse, straight or curly

    • Large or small diameter

    • Long, medium or short

    Correct Answer
    A. Coarse, medium, or fine
    Explanation
    Hair texture refers to the thickness or diameter of individual hair strands. It can be classified into three categories: coarse, medium, or fine. Coarse hair has a larger diameter and is generally thicker and stronger. Medium hair falls in between coarse and fine hair, with a moderate diameter. Fine hair, on the other hand, has a smaller diameter and is generally more delicate and prone to breakage. This classification helps in understanding the characteristics and needs of different hair types for appropriate care and styling.

    Correct Answer
    A. Surfactant
    Explanation
    A surfactant is a substance that acts as a bridge between oil and water, allowing them to mix or emulsify. Surfactants have a unique structure that consists of both hydrophilic (water-loving) and hydrophobic (water-repelling) parts. The hydrophilic part attracts water molecules, while the hydrophobic part attracts oil molecules. This dual nature of surfactants allows them to lower the surface tension between oil and water, enabling them to mix together. Therefore, a surfactant is the correct answer in this case.

    Correct Answer
    A. Hydrophilic
    Explanation
    The water-loving head of a surfactant molecule is hydrophilic. This means that it has an affinity for water and can dissolve or mix well with it. Surfactant molecules are composed of a hydrophilic head and a hydrophobic tail. The hydrophilic head attracts water molecules, while the hydrophobic tail repels water and is attracted to nonpolar substances. This property allows surfactants to reduce the surface tension of water and enable it to spread and penetrate substances that it would not normally be able to.
