How do you use Stargazer Royal Blue hair dye?

To use this dye, start with freshly washed and towel-dried hair. Make sure to put on gloves to prevent staining, and carefully cut the nib of your Stargazer bottle. Evenly cover your hair with dye using a tint brush and leave it to process for 15-30 minutes. After this time, thoroughly rinse your hair to reveal your new brilliant blue hairstyle.

Our Blue Banana Hair Dye Guides contain more information on colouring your hair at home. Before you begin application, make sure to thoroughly read the instructions and always perform a skin patch test. One bottle of Stargazer hair dye typically covers shoulder length hair.

Stargazer Royal Blue Hair Dye On Dark Hair

If used on dark hair, Stargazer Royal Blue hair dye may only give a subtle tint. Apply this deep blue dye to bleached blonde hair for vibrant results or light brown hair for more muted navy tones. To check how this Royal Blue hair dye will look with your hair colour, perform a strand test.

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.
