NIC Cosmetology Written (Theory) ExamHair Care and ServicesHard
A cosmetologist is performing a hair analysis on a client. The client's hair feels fine, is easily tangled, and appears dull. When a single strand is stretched wet, it breaks easily with little to no return. What condition does this indicate, and what type of treatment would be most beneficial?
- ALow porosity; moisturizing conditioner
- BHigh porosity; clarifying treatment
- CNormal elasticity; balancing shampoo
- DPoor elasticity; protein reconstructor
Show answer & explanationAnswer & explanation
Correct answer: D. Poor elasticity; protein reconstructor
Hair that breaks easily when wet and does not return to its original length indicates poor elasticity, suggesting significant damage to the hair's protein structure. A protein reconstructor is specifically designed to strengthen and rebuild these damaged bonds.
Why the other options are wrong
- A. Low porosity means hair resists moisture, but the described breakage points to elasticity issues, not just porosity. A moisturizing conditioner might not provide enough structural repair.
- B. High porosity means hair absorbs moisture quickly, but the primary issue described is breakage due to poor elasticity. A clarifying treatment removes buildup, which is not the main problem here.
- C. Normal elasticity means hair stretches and returns, which contradicts the client's symptoms. A balancing shampoo is for scalp conditions, not structural repair.
Protein Reconstructor
A deep conditioning treatment containing hydrolyzed proteins that penetrate the hair shaft to strengthen and repair damaged internal structures, improving elasticity and reducing breakage.
- Used for severely damaged, weak, or over-processed hair.
- Temporarily rebuilds disulfide bonds and keratin chains.
- Should be followed by a moisturizing conditioner to restore suppleness.
Memory trick: Broken hair, no stretch, protein's the patch, for a strong hair fetch.
