Multiple Choice Questions

  1. Causing factor of dandruff

    • a) Yeast (Specifically, Malassezia globosa)

    • b) Bacteria

    • c) Virus

    • d) Prion

  2. What happens when a person has dandruff?

    • a) Cell production rate decreases

    • b) Cell production rate increases

    • c) Bacterial by-products trigger inflammation

    • d) Less sebum is produced than normally

  3. Common treatments for dandruff

    • a) Zinc pyrithione, acetylsalicylic acid, tar

    • b) Tar, sulfur, acetylsalicylic acid

    • c) Zinc pyrithione, tar, sulfur (While salicylic acid is used, silica and ketoconazole are not typically first-line treatments for dandruff.)

    • d) Salicylic acid, silica, ketoconazole

  4. TRUE statement for hair conditioners

    • a) Quats have a negative charge that bond to negative hair fibers

    • b) Film-formers coat the hair fiber and fill in the holes (Quats have a positive charge, not negative. Protein size doesn't necessarily dictate penetration, and silicones are generally neutral.)

    • c) Protein-based conditioners contain large-sized proteins

    • d) Silicones have a positive charge that bond to negative hair fibers

  5. Highest amount of surfactants generally found in:

    • a) Everyday shampoo

    • b) Baby shampoo

    • c) Dry shampoo

    • d) Dry cleansing shampoo

  6. How do shampoos clean hair?

    • a) Via emulsification

    • b) Via abrasion

    • c) Via dissolution

    • d) All of the above

  7. Main cause of eye irritation when using shampoos:

    • a) Cationic surfactants

    • b) Anionic surfactants

    • c) Silicone conditioners

    • d) Preservatives

  8. Sodium chloride can thicken shampoos that contain:

    • c) Nonionic surfactants

    • d) Cationic surfactants

  9. TRUE for instant hair conditioners:

    • a) Designed to be left on for days

    • b) Used on dry hair

    • c) Used on wet hair

    • d) Protect from heat damage

  10. NOT true for combability testing:

    • a) Living animals are used for the test (Combability testing is typically done in vitro using hair tresses.)

    • b) Artificial or human hair tresses are used

    • c) Evaluates change in grooming force

    • d) Both wet and dry hair can be used

Fact or Fiction?

  • a) Conditioners provide a temporary aid to the hair. Fact. Conditioners improve the feel and manageability of hair, but their effects are largely superficial and don't permanently alter the hair's structure.

  • b) Shampoos that do not foam well do not clean well. Fiction. Foaming is primarily aesthetic. While some surfactants create more foam, cleaning ability isn't directly tied to foam volume.

  • c) Dandruff is a noncontagious infection. Fact. Dandruff is a scalp condition, not contagious.

  • d) Dry shampoos work without soap and water. Fact. Dry shampoos absorb oil and sebum, freshening hair without the need for water.
