Rockabilly® Blue Semi-Permanent Hair Color – Amplified™ European Formula
Rockabilly Blue is one of our strongest true, neutral blue hair dyes. This vibrant, ultra-powerful blue leaves cool tones on virgin, unbleached hair. For head turning results, we recommend lightening hair to a light level 9 blonde and toning hair before use to prevent unwanted hues.
For best results, we recommend pre-lightening your hair using a Manic Panic Flash Lightning® Hair Bleach Kit. Always follow the instructions included with each product.
Always perform a patch test 24 hours before use, as instructed on the packaging.

What is the Amplified Hair Dye Collection?
The Amplified Formula range includes some of the most vibrant Manic Panic shades, with 30% more pigment than the Classic High Voltage® collection.
With proper care, these semi-permanent colours may last longer than typical formulas—ideal for those looking for bold results with extra staying power.
Amplified colours show best on pre-lightened hair, especially at level 10 blonde. Some of the more pigmented shades, such as reds or blues, may add a subtle tint to darker base colours. Results vary depending on hair condition and starting shade.
