Perform predisposition test

Performing a predisposition test, also known as a patch test, is essential before performing a perming treatment
to ensure that the client does not have an adverse reaction to the chemicals used in the process.
Prepare the Testing Area: Choose a small, inconspicuous area on the client’s skin, such as behind the ear or
the inner elbow, to perform the test. Ensure the skin is clean and free from any products or irritants.
Select the Test Products: Use a small amount of the perm solution and neutralizer that will be used during the
perming treatment. These products should be the same formulations and brands that will be applied to the client’s
hair.
Apply the Perm Solution: Using a cotton swab or Applicator brush, apply a small amount of the perm solution
to the testing area. Ensure that the solution is fully saturated on the skin but not dripping.
Apply the Neutralizer: After allowing the perm solution to dry for a few minutes, apply a small amount of the
neutralizer over the same area using a separate cotton swab or Applicator brush.
Wait and Observe: Instruct the client to avoid touching or disturbing the testing area and to wait for at least 24-
48 hours before washing the area. Advise them to monitor the skin for any signs of redness, irritation, itching,
swelling, or other adverse reactions.
Record Observations: Document the client’s reaction to the patch test, including any skin sensitivities or adverse
reactions. Keep detailed records of the test results for future reference.
Evaluate Results: After the specified waiting period, examine the testing area for any signs of irritation or allergic
reaction. If the client experiences any adverse reactions, do not proceed with the perming treatment.
Consultation with Client: Discuss the results of the patch test with the client and explain any potential risks or
concerns. If the client experiences a negative reaction, offer alternative treatment options or advise them to seek
medical advice if necessary.
Document and Consent: Have the client sign a consent form acknowledging that they have undergone a
predisposition test and understand the potential risks associated with perming.
Proceed with Caution: If the client shows no adverse reactions to the patch test, proceed with the perming
treatment as planned. Ensure that you closely monitor the client throughout the treatment for any signs of
discomfort or allergic reactions.
Performing a predisposition test is a crucial step in ensuring the safety and well-being of your clients during
perming treatments. It helps to identify individuals who may be sensitive or allergic to the chemicals used in the
process, allowing you to take appropriate precautions or recommend alternative treatments.
Sectioning for Perming: Sectioning involves dividing the hair into smaller, manageable sections before applying
the perm solution and wrapping the hair around perm rods.

The purpose of sectioning is to ensure even distribution of the perm solution and uniform curl formation throughout
the hair. Sections are typically created based on the desired curl pattern, hair length, and the size of the perm
rods. Sectioning helps the stylist to work systematically through the hair and ensures that each section receives
equal attention during the perming process.
Sections can be divided horizontally, vertically, or diagonally, depending on the hair length and desired outcome.

Perform Sectioning & blocking

Sectioning and blocking are essential steps in the perming process as they ensure even distribution of the perm
solution and uniform curl formation.
Procedure
Prepare the Hair: Start with clean, dry hair that has been detangled and free from any styling products. Ensure
the hair is evenly distributed and neatly combed through.
Divide the Hair: Section the hair into four quadrants by creating a center parting from the forehead to the nape
of the neck and a horizontal parting from ear to ear.Secure each quadrant with clips or hair ties to keep them
separate and manageable.
