Hair ServicesQuestion 362 of 484
A client received a patch test 48 hours ago and the test site now shows redness, swelling, and itching. What is the correct action?
a.Do not perform the color service; advise the client to consult a physician
b.Perform the service but dilute the color with conditioner
c.Switch to 10-volume developer and proceed
d.Perform a second patch test on the other arm and continue
Explanation
A positive patch test (redness, swelling, itching, blistering) means the client is sensitive to ingredients in the formula, most often PPD. The service must not be performed; the client should be advised to consult a physician. Diluting or changing developer does not eliminate the allergen.
