Heads up! We’ve got a shampoo recipe for our fair-haired friends!

Here’s a riddle: what scares blonde and white hair? The colour yellow! If you feel like you’re not getting the joke, that’s because we’re completely serious. Very light hair tends to turn yellow due to pollution, tobacco, the sun, harsh dyes, or unsuitable haircare products. To prevent this from happening or to restore yellowed hair to a cool shine, we’ve developed a recipe for a solid blue shampoo that will turn your hair not strawberry blonde but Blueberry Blonde!

This product is also sometimes called silver or purple shampoo. It cancels out yellowy or brassy tones and refreshes your hair’s shine, while gently washing it. And, with marshmallow root powder and honey, this homemade blue shampoo leaves your hair soft, hydrated, and detangled. It’s a true-blue friend to anyone with fair hair! 

So, fair-headed friends, let’s get ready to go Blueberry Blonde!

How to make blue shampoo

Before you begin

  • SCI (sodium cocoyl isethionate) can irritate your respiratory tract, so it must be handled with caution. Work in a well-ventilated space, wear a dust mask, or both.
  • If you haven’t tried solid shampoo before, keep in mind that it may take your hair some time to adapt, as it’s quite different from liquid shampoo. We recommend giving yourself at least three weeks before reaching a final opinion, as that’s about how long it will take for your scalp to adjust to your homemade solid shampoo! 
  • You can use a coffee grinder to pulverize the SCI. We recommend that you carefully rinse your coffee grinder afterwards and that you do not reuse to process foodstuffs.

  • The chamomile hydrosol and the lemon and chamomile essential oils were chosen for their lightening properties. 
  • Marshmallow root powder is a very useful active ingredient in haircare products, as it helps to detangle your hair and leaves it very soft. 
  • Coconut oil provides much-needed nourishment for bleached hair, which is often very dry.
  • Honey hydrates your hair and will also help remove yellow tones. 
  • The ultramarines counteract yellow tones. 

Steps to follow

Use and conservation

This homemade blue shampoo is formulated for fair hair (blond and white). To use it, just rub the shampoo bar on your scalp or between your hands to produce a lather. We recommend leaving the shampoo on for two minutes before rinsing, to increase its effectiveness.

It is important to let your shampoo dry out between uses. When made in optimal sanitary conditions, it will keep for at least six months, stored in a dry place.

    is the blue powder necessary as pigment? I have the purple powder but it doesnt work for my yellow roots.. is it the blue powder that works better with it ? Thank you!

      Hello Inne,
      We tried using the ultramarine violet alone, without the ultramarine blue, and it didn’t work as well, that’s why our recipe contains both. Also, make sure to leave the shampoo on for two minutes before rinsing, to increase its effectiveness.
      Have a great day!

  • Inne Baert
