For best results Stargazer should be applied to freshly washed, pre-lightened, damp hair. For the brightest results, or when using pastel colours you will get best results on very pale blond hair.

For even results apply using a tint brush. Avoid contact with scalp as staining my occur. A layer of petroleum jelly around the hairline and ears will help prevent staining to the skin. If stains do occur, most can be removed with soap and water or rubbing alcohol.
Each pack comes complete with plastic gloves. Wear these to avoid staining your hands.

Once applied comb the hair until it emulsifies. This helps the hair absorb the dye and ensures a more even coverage.

  • Precautions

    Always read the manufacturers instructions and check the ingredients for anything you may be allergic to.

    Always do a strand and sensitivity test before applying this hair dye.

    Colours will stain natural fibres, textiles, carpets, walls & surfaces as well as any other porous surface so ensure your work area is covered before applying the dye.

    Colour may rub off damp hair onto surfaces so we advise using an old pillowcase for the first few washes.

    Temporary staining may occur to skin but this can be removed with rubbing alcohol or soap and water. Temporary staining to baths, showers and sinks can be removed with household bleach (always check manufacturers instructions before use).

    Avoid contact with eyes. Keep out of reach of children and pets.

Reviews of Stargazer Blue Black

  • I used this for my bangs. I used it on bleached hair, and it came out very bright, nothing like I expected it. But still lovely. I can't really tell if I got this result because of my weird hair, or if it really is supposed to be bright.
  • Hello, I'm an Italian girl and use google translator to write, so if the grammar is a little bad for that matter. However, I would dye my hair this color .. bleaching but I would not, if you know the color adheres to the same? I have brown hair at the roots and call it a golden-red on the tips .. can you tell me, if this does not join, a type of dye that can be used without TEMPORARY bleaching? type that uses katy perry ..
  • This is the best blue-black I have ever used!
  • What sort of result would I get if I have medium light brown hair? Will it go greenish or will I get a true blue black color? :)
  • Really decent color. It's faded a good bit into week 3 now but hasn't turned an ugly color.
  • Really beautiful color and fades to a nice shade of light blue but trying to get this color out of my hair and go back to natural is the worst process I've ever experienced of all my hair-coloring.
  • Well this dye fades so fast. The color is pretty dark even on bleached hair. I think this dye works best as stripes, dip dye or bangs
