Licensed hairstylists and colorists performing permanent color services with the Revlonissimo Colorsmetique line. Not intended for a consumer to apply alone — it has no coloring or lightening effect by itself and must be professionally mixed with a separate permanent color product.

A colorist reaches for 20 volume specifically when a service calls for gray coverage or a modest lift rather than dramatic lightening; choosing a higher-volume developer (30 or 40) for that same job would over-process the hair unnecessarily.

1. Select Revlonissimo Colorsmetique permanent color for the desired shade.
2. Mix 1 part color with 1.5 parts Cream Peroxide 20 Volume in a non-metallic bowl.
3. Apply evenly to hair following standard sectioning and application technique for the service.
4. Process for approximately 30–45 minutes, checking color development periodically.
5. Rinse thoroughly, then shampoo and condition.

Pros:

• Cream consistency mixes evenly and clings to hair better than a liquid peroxide for controlled application
• 20 volume is a versatile mid-strength option for gray coverage and tone-on-tone or modest-lift color services
• Formulated to work specifically with the Revlonissimo Colorsmetique shade line for predictable, tested results

Cons:

• Must be mixed with a separate permanent color product — it does nothing to hair used alone
• Not intended for consumer/DIY application; requires professional mixing ratios and a strand/skin test
• Only lifts approximately two levels, so it isn't suited to significant lightening or bleaching services
