New Mexico Cosmetology Practice Exam 2025 – Complete Preparation Guide

Question: 1 / 400

Which ingredient is commonly used in moisturizing hair products for curly hair?

Petroleum jelly

Coconut oil

Coconut oil is commonly used in moisturizing hair products for curly hair due to its beneficial properties. It is rich in fatty acids that help to penetrate the hair shaft, providing deep moisturization and reducing protein loss. This is particularly important for curly hair, which tends to be drier and more prone to frizz. Coconut oil enhances the natural curl pattern, adds shine, and makes curls more manageable. Its emollient properties also help to smooth the hair cuticle, which can improve overall texture and appearance.

While other substances like petroleum jelly might create a temporary seal on the hair's surface, they do not offer the same nourishing benefits as coconut oil. Sodium chloride is primarily a thickening agent or preservative in products, not a moisturizing ingredient. Alcohol can often have a drying effect on hair, which is counterproductive for people with curly hair seeking moisture.
