How To Use Manic Panic Bad Boy Blue Hair Dye

To prevent staining to the skin make sure to put on protective gloves and put on an old t-shirt or use an old towel around your shoulders.

Rinse your hair with cool water to complete your new blue hairstyle.

Always make sure to perform a patch test before dyeing your hair and read the instructions that come with the product.

Manic Panic Bad Boy Blue On Dark Hair

Manic Panic Bad Boy Blue is likely to give a subtle tint to dark hair colours, particularly brown but for vibrant blue colour, apply to bleached hair that is level 9. With blue hair dye, it is important to tone your hair first to avoid any unwanted undertones and brassy hues.

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.
