What is the purpose of a strand test?

• A. To Determine Color Shade
• B. To Test Strand Strength
• C. To Determine How The Hair Will React To A Chemical Product
• D. To Assess Scalp Moisture

Answer: (C)

A strand test is used to see how hair will react to a chemical product before applying it to the whole head. By applying a small amount of product to a tiny strand and letting it process under the usual conditions, you can observe how much lift or deposit occurs, how the hair takes on the color or texture, and whether the processing time will be appropriate. This helps tailor the product strength and processing duration to that individual’s hair, reducing the risk of over-processing, under-processing, or unexpected results. It also gives you a preview of the final result, so you and the client can agree on the desired outcome before committing to the full service. It isn’t primarily about testing color shade accuracy, strand strength, or scalp moisture. Those factors are addressed separately, while the strand test focuses on predicting the hair’s chemical response and processing behavior.
