Delaware Cosmetology and Barbering Practice Exam

How can a cosmetologist determine a client's hair type?

1. By assigning a color code

2. By evaluating hair's texture, density, and porosity

3. By client questionnaire alone

4. By observing natural curls only

The correct answer is: By evaluating hair's texture, density, and porosity

A cosmetologist can determine a client's hair type by evaluating several key factors, including the hair's texture, density, and porosity. Texture refers to the diameter of individual hair strands, which can be fine, medium, or coarse. Understanding texture helps in selecting the right products and services tailored to the client's specific needs. Density indicates how many strands of hair are present on the scalp, affecting how full or thin the hair appears. A higher density can mean more volume, while lower density can suggest a need for products that create the illusion of thickness. Porosity describes how well the hair absorbs moisture and products, which is crucial for choosing the right treatments and products to maintain and enhance the health of the hair. Hair can be low, medium, or high porosity, and this information helps determine how effectively moisture and color treatments will be absorbed. By evaluating these three factors, a cosmetologist gains a comprehensive understanding of the client's hair type, enabling them to provide personalized recommendations for care and styling. This approach is far more effective than relying on a questionnaire alone or simply observing curls.
