Demi-Permanent Hair Color Frequently Asked Questions

Demi-permanent hair color is a gentle, ammonia-free formula mixed with a low-volume developer. It deposits color onto the hair's surface without fully penetrating the cuticle, offering a subtle, natural-looking transformation. It’s ideal for enhancing existing color, blending grays (up to 60%), and adding shine without permanent commitment.

Revlon’s demi-permanent hair color lasts up to 28 washes, making it a low-commitment option that gradually fades without harsh root grow-out effects.

Semi-permanent: Lasts 3–6 washes, doesn’t require a developer, and sits on the hair’s surface. Best for short-term changes.

Demi-permanent: Lasts 20–28 washes, uses a low-volume developer, and penetrates slightly deeper for longer-lasting results. Ideal for subtle enhancements or gray blending.

To fade or remove demi-permanent dye:

• Use clarifying shampoo to speed up fading.
• Try DIY methods like vitamin C powder mixed with anti-dandruff shampoo.
• For professional results, consider a color remover, which gently eliminates artificial pigments without damaging hair

No, Revlon’s demi-permanent formulas are ammonia-free and gentle. They use low hydrogen peroxide levels, which minimize damage while enhancing shine and hydration.

Mixing these types is not recommended as they serve different purposes. Permanent dye lifts and deposits color deeply, while demi-permanent only deposits pigment. Combining them may lead to unpredictable results.

1. Mix the ammonia-free colorant with the developer.
2. Apply from roots to ends for full saturation.
3. Leave on for 20 minutes.
4. Rinse, shampoo, condition, and treat with the leave-in serum from the ColorSilk Tone+Gloss+Care for added hydration and shine.
