Which conditioner type is designed to deposit proteins into the cortex?

• A. Instant conditioner
• B. Normalizing conditioner
• C. Moisturizing conditioner
• D. Body-building conditioner

Answer: (D)

Protein-based conditioning is aimed at strengthening hair by depositing proteins into the cortex, which is the inner part of the strand responsible for strength and resilience. When hair is damaged, adding these proteins helps fill gaps and reinforce the keratin structure from within, improving body and reducing breakage. That’s why this type of conditioner is described as body-building — it’s specifically designed to build up the internal strength of the hair. Other conditioners focus on surface benefits: instant conditioners provide quick slip and surface moisture for detangling, moisturizing conditioners add moisture to the cuticle, and normalizing conditioners balance pH and smooth the cuticle. They don’t target the cortex the same way, which is why they aren’t described as depositing proteins to strengthen the core of the hair. Use protein conditioners as part of a balanced routine, since too much protein can make hair feel stiff.
