IGORA Royal Fashion Lights is a professional-use product for licensed hair colorists, not a home hair-color kit. It's formulated for use on level 6 (dark blonde) bases and darker, for clients wanting high-contrast fashion highlights or lift without a separate pre-lightening step. Applying it correctly requires professional mixing with developer, sectioning technique (foiling, balayage, or similar), and judgment about processing time — it isn't intended to be applied by the client themselves.

For a colorist working on a dark or previously colored base, Fashion Lights removes a step that highlighting services often require: pre-lightening before toning. Because it lifts up to five levels and tones in the same application, high-contrast foil or balayage work on darker hair can be done without first bleaching those sections separately. The built-in Bonding Technology and Anti-Metal Technology are there to reduce the extra products a colorist would otherwise need to reach for — a bond additive and a metal-neutralizing pre-treatment — to get a controlled, even result on chemically unpredictable bases.

• Mix IGORA Royal Fashion Lights color cream with IGORA Royal Oil Developer at a 1:1 ratio, using 9% (30 volume) or 12% (40 volume) developer depending on the level of lift needed.
• Apply off-scalp only, using a foiling, balayage, or similar highlighting technique, to sections of hair on level 6 or darker bases.
• Process for 30 to 45 minutes — toward the longer end when lifting a previously tinted base — checking development as needed.
• Rinse, then shampoo and condition following standard aftercare.

This is a professional colour service performed by a trained colorist in-salon; it is not intended for home application.

Pros:

• Lifts up to 5 levels without a separate pre-lightening step, condensing lift and tone into one application for dark or previously colored bases.
• Built-in Bonding Technology is designed to help protect the hair's internal structure during the lifting process, without needing a separate bond-protecting additive.
• Anti-Metal Technology binds metal ions in the hair, supporting more even color development without a separate metal-neutralizing pre-treatment.

Cons:

• Requires professional mixing with developer and off-scalp application technique — not suitable or sold for home/DIY use.
• Only formulated for level 6 bases and darker, so it isn't the right product for lightening hair that's already pre-lightened or very pale.
• Processing takes 30 to 45 minutes, which adds to appointment/chair time compared with a single-step gloss or toner.
