Which of the following statements is true of lighteners?

• A. Used to Add Melanin to the Hair
• B. Used to Add Polymers and Melanin
• C. Generally Applied to Wet Hair
• D. Used to Diffuse or Remove Pigment

Answer: (D)

Lighteners are designed to remove or diffuse pigment from the hair. They work by oxidizing melanin in the cortex, breaking down pigment molecules so they can move out into the lightening mixture and lighten the color. This action is about lifting color, not adding color or substances—so they don’t add melanin or polymers. Because the goal is controlled lift, lighteners are typically used on dry or appropriately prepped hair to ensure even processing; applying to very wet hair can dilute the product and produce uneven results.
