DESCRIPTION
How Much Manic Panic Rockabilly Blue Do I Need?
With the 8oz pots, hair at shoulder length should only need one pot to saturate a full head. Shorter hair between a pixie cut and a bob may have only needed one 4oz pot of the Manic Panic colours for a full head application in the past; however, with the 8oz formulas and hair at this length you can guarantee there will be leftovers which can be saved for future touch-ups due to the resealable container.
How To Dye Your Hair With Manic Panic Rockabilly Blue
Apply your Manic Panic Rockabilly Blue dye to towel dried hair using a tint brush whilst wearing gloves. Once you have saturated each desired section with the colour, gently comb through these to ensure an even application. Allow the Rockabilly Blue dye to process for 30 minutes before thoroughly rinsing your hair with cold water and revealing your new vibrant look!
Always make sure to carry out a patch test before dyeing your hair and a strand test to check the results on your hair colour.
What Colour Does Manic Panic Rockabilly Blue Fade To?
Rockabilly Blue is an accurate blue that fades true to tone. This particular dye is one of the most vibrant within the Manic Panic collection and when cared for correctly will provide a vibrant appearance for some time. As Rockabilly Blue begins to fade, enjoy its neutralised pastel tone.
Please Note: Hair dye results may vary depending on your hair type, base colour and hair porosity; the image of the hair dye is a representation of the finished colour and is not a guaranteed result. This dye is not suitable for use on hair with more than 10% grey coverage.
Patch Test
Always perform a patch test 48-24 hours before use, following the instructions on the packaging.
