In order to establish the length of time a lightening agent must be let on the hair, it is necessary to first give a/an:

Strand test
Allergy test
Oxidizing test
Patch test

The correct answer is: Strand test

A Strand test is necessary before applying any lightning agent to the hair. This test will determine how long the product should be left on the hair, based on the hair's texture, color, and porosity. This is important because each individual's hair will react differently to the lightning agent and leaving it on for too long can cause damage or over-processing. B, C, and D are incorrect because these tests do not determine the length of time the lightening agent should be left on the hair. A Patch test is used to test for any allergic reactions to the product and is typically done 24-48 hours before applying the lightening agent. An Allergy test is also done before applying the lightening agent to determine if the individual will have an allergic reaction to the product. An Oxidizing test is used to test the strength of the peroxide in the lightening agent and is mainly used in professional settings to ensure the proper mixing ratio for the desired result.
