After initial application of oxidative color what happens?

• A. The Hair Strand Shrinks
• B. The Hair Strand Swells
• C. The Color Fades Immediately
• D. The Cuticle Tightens

Answer: (B)

Oxidative color works by using an alkaline developer that raises the hair’s pH, causing the cuticle to lift and the strand to swell. This swelling opens the outer layer so color molecules can penetrate into the cortex and begin the oxidation process. So the initial effect is the hair strand swelling, not shrinking or tightening, and color won’t fade immediately—it starts to deposit and develop as oxidation proceeds.
