Which statement describes non-oxidative color that has large and small color molecules (that penetrate the cuticle and enter the cortex) as described in the material?

• A. Semi-permanent
• B. Demi-permanent
• C. Temporary color
• D. Oxidative color

Answer: (A)

Non-oxidative color works without an oxidizing developer, so color comes from dye molecules depositing in the hair rather than a chemical reaction inside the cortex. In semi-permanent color, you have both large and small dye molecules. The small molecules can pass through the cuticle and enter the cortex, while the larger ones mainly stay in the cuticle. This combination gives color that lasts for several shampoos and gradually fades, without lifting the hair or changing its structure. Temporary color, by contrast, relies mostly on large molecules that sit on the surface and wash out quickly. Oxidative color uses a developer to open the cuticle and form pigment inside the cortex, producing longer-lasting results.
