Each pack of L'Oreal Paris Casting Creme Gloss is designed for one complete application.

Immediately wipe off any color that gets on your skin with a damp cloth or a dedicated color-remover wipe. For best results, apply a barrier cream (like petroleum jelly) around your hairline before application.

Yes, it can be used on previously colored hair, but always perform a strand test first to predict the final color result, as it can vary based on your existing hair color.

Ensure you followed the development time precisely. Use color-safe hair products and avoid excessive washing or heat styling, which can accelerate fading.

Always use the included conditioning treatment. For very dry hair, consider a deep conditioning treatment a few days after coloring. Ensure you performed a strand test and followed instructions to avoid over-processing.

Semi-permanent colors tend to fade. With subsequent washes, the color may lighten. For unevenness, ensure thorough and even application during the coloring process.
