FCTC Test Technical Reading and Recall 1 — Questions and Answers
Question 1: A technical insert states that a toner should remain on hair 'no longer than 20 minutes at room temperature.' What does the phrase 'room temperature' specify in this context?
- The product must be stored in a warm room before use
- The service should be performed without applying additional heat sources (Correct answer)
- The salon's thermostat must be set to exactly 70°F
- The toner requires a heated cap to activate properly
Correct answer: The service should be performed without applying additional heat sources
In technical product literature, 'room temperature' means no supplemental heat (dryer, lamp, or heat cap) should be applied; the product works through ambient warmth alone.
Question 2: A cosmetology textbook states that a permanent wave solution 'breaks disulfide bonds.' What does the term 'disulfide bonds' refer to?
- Hydrogen bonds between water molecules in the hair cortex
- Chemical links between sulfur atoms that give hair its natural shape (Correct answer)
- The bonds between the cuticle scales and the cortex layer
- Ionic bonds formed when alkaline products contact the scalp
Correct answer: Chemical links between sulfur atoms that give hair its natural shape
Disulfide bonds are sulfur-to-sulfur chemical links within the cortex that determine hair's natural curl pattern; permanent wave solution chemically reduces these bonds to allow reshaping.
Question 3: A product directions sheet states to perform a '24-hour patch test prior to any oxidative color service.' What is the primary reason the instructions specify 24 hours?
- To allow the colorant to fully oxidize before application
- To give the client time to wash their hair before the appointment
- To allow sufficient time for an allergic reaction to develop and become visible (Correct answer)
- To ensure the color formula is mixed to the correct consistency
Correct answer: To allow sufficient time for an allergic reaction to develop and become visible
Allergic (hypersensitivity) reactions to oxidative dye ingredients such as p-phenylenediamine can take up to 24–48 hours to manifest, so the patch test window must be long enough to detect a reaction before service.
Question 4: A technical reference describes a chemical service as 'exothermic.' According to standard terminology, what does exothermic mean?
- The product must be mixed with cold water to activate
- The chemical reaction releases heat as it processes (Correct answer)
- The product is applied under external infrared heat
- The formula expires when exposed to high temperatures
Correct answer: The chemical reaction releases heat as it processes
Exothermic describes a chemical reaction that releases energy in the form of heat; in cosmetology this is important because the generated heat can affect processing time and scalp safety.
Question 5: A label on a scalp conditioner reads 'for external use only.' In technical language, what does this instruction communicate to the practitioner?
- The product may only be used on the exterior sections of the hair strand
- The product is formulated solely for use on outside-facing hair layers
- The product must not be ingested, inhaled directly, or introduced inside the body (Correct answer)
- The product is intended for use outdoors in natural light only
Correct answer: The product must not be ingested, inhaled directly, or introduced inside the body
The phrase 'external use only' is a standard safety directive meaning the product is designed to contact the outer body surface and must not be swallowed, inhaled, or applied to mucous membranes or open wounds.
Question 6: A technical manual states that semi-permanent color 'does not contain a developer and deposits pigment only.' What can a practitioner conclude from this statement?
- Semi-permanent color can lighten natural hair pigment during processing
- Semi-permanent color requires a high-volume developer for maximum deposit
- Semi-permanent color cannot lighten the hair because no oxidation occurs (Correct answer)
- Semi-permanent color must be mixed with a neutralizer before application
Correct answer: Semi-permanent color cannot lighten the hair because no oxidation occurs
Because semi-permanent color contains no developer (hydrogen peroxide), no oxidative reaction takes place; without oxidation the natural melanin cannot be lightened, so the color only adds tone without altering base depth.
