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.
- 39 g (39%) SCI
- 15 g (15%) chamomile hydrosol or demineralized water
- 18.6 g (18.6%) coconut oil
- 12 g (12%) ghassoul clay
- 6 g (6%) marshmallow root powder
- 1 g (1%) ultramarine blue
- 3.3 g (3.3%) ultramarine violet
- 1.5 g (1.5%) 10% chamomile essential oil
- 1.5 g (1.5%) lemon essential oil
- 2.1 g (2.1%) honey
- 3 small stainless steel bowls
- Components to make a double boiler
- 1 small silicone spatula
- 1 scale, accurate to 0.1 g
- A few pipettes
- A few ramekins
- A few spoons
- A coffee grinder or mortar and pestle
- Silicone molds
- A dust mask or stove hood
Good to know!
- 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
- Prepare and disinfect your equipment and workspace.
- Grind the SCI into a powder using a mortar and pestle or coffee grinder, then pour it into a bowl.
- Weigh the chamomile hydrosol or demineralized water, coconut oil, and honey in a ramekin.
- Weigh the powders (the ghassoul clay, marshmallow root powder, and ultramarines) in a ramekin and set aside.
- Weigh the essential oils in a ramekin and set aside.
- Add the contents of ramekin containing the hydrosol or the water to the bowl containing the SCI. Heat on the double boiler, mixing thoroughly as it melts.
- When the contents of the bowl have all melted, remove the bowl from the heat and add the powders. Mix well with the spatula until a compact paste forms.
- Add the essential oils and mix well.
- Transfer the mixture to the molds, compacting well.
- Allow your DIY shampoos to dry for 24 hours.
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.
