Fine hair, which is generally less resistant, may appear to process in what manner when color is deposited?

• A. Darker
• B. Lighter
• C. More even
• D. No change

Answer: (A)

Resistance of the hair to color determines how much pigment actually stays in the strand during deposition. Fine hair has less mass and a less dense cuticle barrier, so pigment molecules penetrate more easily and deposit more readily. That means the same color formula and processing time will place more color into each fine strand, making the overall result appear darker than on hair with higher resistance. If you’re dialing in a shade on fine hair, you’d typically expect a deeper result and may need to adjust formulas or timing to avoid an unintended too-dark outcome.
