Licensed hair colorists and salon professionals performing permanent color services with Joico's LumiShine Permanent Crème Color line. It's the developer to reach for when a formula calls for significant lift — up to three levels lighter, high-lift blonding with 10-series shades, or covering resistant grey with -00 shades.

It is not intended for consumers mixing their own color at home; correct use depends on selecting the right LumiShine shade, following the brand's mixing ratio, and monitoring processing time, which is professional-level knowledge.

The reason to reach for the 30-volume LumiShine developer specifically is lift: among Joico's LumiShine developer range (5, 10, 20 and 30 volume), this is the strength built for services that need the most lightening in one process, such as high-lift blonde formulas with the 10-series shades or breaking through resistant grey with -00 bases.

Because it's engineered around LumiShine's ArgiPlex technology, using it with LumiShine color — rather than substituting a generic 30-volume developer — keeps the color line's shine and hair-condition claims intact as the brand intends. It's a formulation choice for colorists building or adjusting a specific lift level, not a general-purpose product meant for every service.

This product is intended to be mixed and applied by a professional colorist as part of a Joico LumiShine permanent color service.

• Select the LumiShine permanent crème color shade required for the service.
• Combine the color and 30 Volume Crème Developer at a 1:1 ratio in a non-metallic bowl, mixing to a smooth, even crème.
• Apply promptly to dry, unwashed hair following standard sectioning and application technique for the service being performed (full lightening, high-lift blonding, or grey coverage).
• Process for the time specified by the LumiShine color system for the shade and level of lift needed, checking a test strand as needed.
• Rinse thoroughly, then shampoo and condition to complete the service.

Pros:

• Formulated specifically to work with LumiShine's ArgiPlex technology, so results match what the color line is designed to deliver
• 30-volume strength gives colorists real lifting power for high-lift blonding or resistant grey coverage in a single process
• Standard 1:1 mixing ratio keeps formulation math simple and consistent across the LumiShine developer range

Cons:

• Only formulated for pairing with LumiShine permanent crème color — not a general-purpose developer for other color lines
• 9% peroxide at this volume carries real risk of over-lightening or scalp irritation if mixing ratios or processing time aren't followed correctly
• Requires professional color-formulation knowledge; not designed as a stand-alone or beginner-friendly product
