When correcting an over-lightened strand, which approach is appropriate?

• A. Apply a darker shade directly to balance the strand.
• B. Avoid using any filler and proceed with a normal lift.
• C. Use a filler to rebalance porosity and level, then apply a suitable shade with controlled lift to avoid further damage.
• D. Lighten further and hope for even result.

Answer: (C)

When correcting an over-lightened strand, the priority is to restore porosity and create an even base before applying more color. An over-lightened area has damaged, uneven cuticles and uneven porosity, so simply depositing darker pigment or lifting further can lead to patchy results. Using a filler rebalances porosity and level, giving the hair a more uniform canvas so pigment can deposit evenly. After the filler, apply a suitable shade with controlled lift to avoid adding more damage while achieving the desired tone. Lifting more would risk further damage to already compromised hair, and skipping the filler leaves porosity differences unresolved, which can cause patchy color.
