UNIT 11: HS-CSI-11 Properties of the Hair and Scalp



Annotation:

The structure of hair, its chemical composition, growth cycles, and hair analysis will be covered in this lesson. Students will create a model structure of the hair and conduct proper hair analysis. Students will be able to evaluate terminal and vellus hair using a microscope. Students will look at the disorders of the hair and scalp and identify when a client should be declined for a service.

Students with Disabilities:

For students with disabilities, the instructor should refer to the student's IEP to be sure that the accommodations specified are being provided. Instructors should also familiarize themselves with the provisions of Behavior Intervention Plans that may be part of a student's IEP. Frequent consultation with a student's special education instructor will be beneficial in providing appropriate differentiation.




GPS Focus Standards:


HS-CS-I-9 Students will identify the basic histology of the hair and skin, their diseases and disorders, and corrective treatments.

a. Identify and compare the structure of hair.

b. Investigate and identify samples of hair textures.

c. Compare the various natural hair growth patterns on live models.

d. Identify the scientific terms for head and facial hair and differentiate between them.

e. Demonstrate hair analysis, using density, porosity, and elasticity as scientific indicators.

f. Identify and compare the physical and chemical actions that damage the hair structure.

g. Demonstrate safety and infection control procedures used in hair and scalp treatments

h. Identify the most common diseases and disorders of the skin and hair and explain their origin.

i. Differentiate between corrective treatments for conditions that may be treated in a salon and those that must be referred to a physician.


GPS Academic Standards:

SCSH5 Students will demonstrate the computation and estimation skills necessary for analyzing data and developing reasonable scientific explanations.
ELA10RC3 a) Demonstrates an understanding of contextual vocabulary in various subjects.
SCSh4 Students will use tools and instruments for observing, measuring, and manipulating scientific equipment and materials.



Enduring Understandings:

The structure, growth and composition of hair are essential to a cosmetologist. Knowledge of the histology of hair provides a fundamental base for decision making in salon services. Cosmetologists recognize the commonplace hair and scalp conditions, and are knowledgeable of certain scalp diseases and disorders that can be treated by a cosmetologist or physician.


Essential Questions:

  • What makes up hair?

  • Is hair alive or dead? Explain your answer.

  • How does hair grow?

  • How can members of the same family have different colors of hair?

  • Why should you perform a hair analysis before a service? What will it reveal to the cosmetologist?

  • How does the understanding of hair structure prepare a cosmetologist to be successful in their field?

  • Why does a cosmetologist have the responsibility of recognizing skin infections, disorders, and diseases?

  • How does infection control effect client services?

  • What are the different factors that should be considered in a hair analysis?

  • What are the characteristics of hair disorders?

  • What are the different treatments that can be performed for hair disorders?


Knowledge from this Unit:

Students will be able to:



  • Explain the histology of hair structure and how it relates to salon services.

  • Describe the structure of the hair root.

  • Describe the structure of the hair shaft.

  • Identify the chemical composition of hair.

  • Outline the growth cycle of hair.

  • List the elements of a proper hair analysis.

  • Recognize signs of hair and scalp disorders and diseases.

  • Explain the recommended treatments for the disorders and diseases.

  • Distinguish when to decline a service for the hair or scalp and refer client to physician.


Skills from this Unit:

Students will:



  • Perform a proper hair analysis, including the following:

  • Analyze hair through a microscope and evaluate its structure.

  • Make recommendations for services based on hair analysis.

  • Select the best procedures and products for hair services based on hair analysis.

  • Perform a professional hair and scalp consultation.

  • Conduct safety and infection control procedures while performing services.

  • Demonstrate proper hair and scalp treatments.
