• 35 g of Sodium cocoyl isethionate (SCI)
• 5 g of Sodium coco sulfate (SCS) *
• 15 g of water (tap water, yes yes!)
• 10 g of organic argan oil
• 20 g of organic arrowroot starch + a little more to dust the molds
• 7 g of organic nettle powder
• 6 g of shikakai powder
• 2 g of organic whole ylang-ylang essential oil
• 1 g of Eco preservative
• silicone mold (A silicone muffin tin works too.)

*You can leave out the SCS and use 40 g of SCI in total.

WARNING: SCS and SCI are irritating to the respiratory tract and mucous membranes in powder form. Handle gently to avoid making the powder “fly”. For extra protection, wear a dust mask (N95) and safety glasses. Once the recipe has dried, the solid shampoo is completely safe. No need to wash your hair in chemist's gear, come on! Hahaha. ;)

1. Dust the silicone molds with a little arrowroot starch and remove the excess. This step makes unmolding easier.

2. In a double boiler, combine the surfactant(s) (SCI/SCS) and the water. Stir until the granules are melted or well softened.

3. Add the argan oil. Mix until you get a smooth, sticky paste.

4. Remove from heat and add the arrowroot starch, nettle, shikakai, essential oil and Eco preservative.

5. Let cool a few minutes, until the paste is lukewarm. Be careful not to wait too long since it hardens fairly quickly.

6. Fill one 100 g silicone mold or two 50 g ones.

7. Cool in the freezer for 20 minutes, then unmold. Let dry for 2 to 3 days (ideally a week) so the water has time to evaporate before using.

Rub the shampoo bar on wet hair until the bar makes a nice lather. Rub the scalp to dislodge sebum, let sit a few minutes, then rinse. Repeat a second time if needed.

Let the shampoo bar dry outside the shower or, at least, out of reach of the water spray to maximize its lifespan. Do not store the shampoo in a closed container. The shampoo bar lasts weeeeeks, even months depending on use.

It's life-changing!
