Shades of blue are an exciting, vibrant choice when it comes to coloring your hair- they are versatile enough to pair well with most outfits, and yet unique enough to stand out gorgeously in a sea of blondes and browns. Moreover, blue also makes a chic combination with natural indian hair shades like browns and blacks and can be worn as highlights, ombre, or even balayage. No wonder then, that most people are eager to go blue, making our Rudolphi Blue and Crinkle Violet the perfect choice for them. However, blues can be a little tricky to master, and if not careful, you may not really end up with your preferred shade of blue. Check out our comprehensive guide about common mistakes when it comes to trying out blue hair dye, so you can ensure that you avoid them and always achieve the perfect results!

Your black/brown hair is not bleached or pre-lightened.

    It is common for some to assume that depositing blue on unbleached hair that are naturally brown or black will give it a deep black blue tint, but this is not true. Blue will not show up at all on unbleached hair, so avoid this mistake at all costs.

    Your hair is bleached, but the level is not high enough!

      Blue needs a higher hair level, much higher than warmer shades like reds and oranges, to show up properly on your hair. If your hair isn’t bleached to a higher level, and is currently at a level 4-6 for instance, your blue may turn your hair just back to your original dark brown. The ideal hair level for blue to show up is at level 8 to 10. Always remember, the higher your hair level, the more vibrant your blue will be.

      Rudolphi Blue + Yellow Dye will NOT result in green hair

        Generally, as the color wheel has taught us, mixing blue and yellow pigments gives off a green shade. However, this rule does not apply to our Rudolphi Blue, due to the fact that it contains some amount of Violet pigment, which upon reacting with yellow pigments does not result in green. So, in effect, mixing yellow with our Rudolphi Blue would result in an ashy brown.

        This is the reason why our Rudolphi Blue, unlike blue dyes by other brands, does not result in a green upon fading. The violet pigment in our blue causes it to fade into a lovely ashy shade, which is quite in trend at the moment.

        Another trick to help you achieve a true, power packed blue is toning. Upon bleaching, naturally black or brown hair can often give brassy undertones instead of turning a bright blonde. Toning is a process done post bleaching, using a purple conditioner or shampoo, to get rid of unwanted brassy tints on bleached hair. This helps you achieve a light and even blonde base to ultimately give you a more vibrant, true blue. In case you have gone for two rounds of bleach, chances are that your hair is already quite light and porous, meaning that toning may not be necessary and can be omitted. 

        A rule of thumb to remember when coloring your hair is to always do a strand test before dyeing larger sections. If you are not receiving your desired shade on the strand, another round of bleach may be necessary and should do the trick.
