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-III-16. Students will demonstrate timed relaxer applications using mannequins or clients.

    Applications performed will include virgin relaxers and retouch relaxers. Students will

    evaluate special problems that could occur while relaxing hair.

     a) Demonstrate timed virgin and retouch relaxers.

     b) Record information from relaxer services on client record card.

     c) Evaluate special problems’ area of concern in hair relaxers and assess methods of

    corrections.

    HS-CS-III-17. Students will perform hair relaxer services using proper safety, infection control, and

    Hazardous Duty Standards Act in all procedures.

     a) Describe safety standards and precautions when performing hair relaxer services.

     b) Perform hair relaxer services using safety procedures and infection control guidelines.

GPS Academic Standards:

    SCSh2 Students will use standard safety practices for all classroom laboratory and field

    investigations.

     a) Follow correct procedures for use of scientific apparatus.

     b) Demonstrate appropriate techniques in all laboratory situations.

     c) Follow correct protocol for identifying and reporting safety problems and violations.

Enduring Understandings:

    A good record of previous services enables the hairdresser to provide quality consultations. It is important

    to realize that correct procedure and timing affect the outcome of the relaxer and that overlapping

    products can cause breakage.

Essential Questions:

    ; If a hairdresser takes too long to apply a product what can happen?

    ; What chemical process takes place during a relaxer?

    ; What chemical process takes place during the neutralizing stage?

Knowledge from this Unit:

    Students will be able to:

    ; Decide if a client needs a retouch or a virgin application.

    ; Know how to analyze and fill out a record card.

    ; Recognize special problems.

    ; Know recommendations for correction of special problems.

Skills from this Unit:

    Students will:

    ; Perform timed virgin and retouch relaxers using thioglycolate and sodium hydroxide.

    ; Record information on a record card.

    ; Correctly analyze hair structure prior to service.

    ; Use safety and infection control procedures.

    ; Prevent chemical burns when using relaxing products.

    ; A virgin relaxer is for hair not previously relaxed. The procedure is in three steps. Begin at the

    midshaft which is called the cold shaft, proceed to the part of the scalp known as the heat zone, and

    pull through the ends which may be porous.

3. Review no-base and base.

    ; No-base means the service does not require a protective base on the scalp prior to the relaxer.

    (Special note: all relaxers require a base around the hairline and ears.)

    ; Base means the service requires the application of base over the entire scalp.

    4. Discuss the terms lye and no-lye. These are terms used to describe the chemicals in the relaxer. If the relaxer

    has lye it is stronger than no-lye and refers to sodium hydroxide perms. If the relaxer has no- lye it is the

    weaker product and refers to thiogycolate perms. These products must never be overlapped due to different

    chemical properties and will result in hair breakage and damage.

5. Give students a copy of the Procedures for Relaxers Handout. Go through each step and make sure that

    students understand every step. Let students ask questions. Once students understand the procedures, give

    them the Relaxers Chemical Texture Services Lab Sheet.

    6. Explain and demonstrate each procedure one at a time. Have the students practice and complete their lab

    sheets using the procedure sheet as guide. Provide student commentary and feedback after each service

    check.

7. Have students perform each procedure for a third time as you grade them using the Relaxers Grade Sheet.

    8. Summary: Discuss with students how their procedures went. Allow students to provide feedback, tips, and

    questions for you and other students. Students need to be comfortable with each procedure to ensure they

    successfully complete the Mastery Test.

Culminating Unit Performance Task Title:

     Mastery Test

    Culminating Unit Performance Task Description/Directions/Differentiated Instruction:

    To prepare for this test, have students roll a curly perm on a mannequin using grey rods. Allow it to

    completely dry. Students will take the hair down and pick it out into an afro. Give each student a different task

    card. They will complete their task in a timed setting using the proper method with teacher observation. They

    may not talk or use notes. To make task cards: write one of the procedures on enough index cards for the
