Shampoo bars have gained popularity as the desire to decrease our waste output has increased. They require no bottle as they are solid so no landfill or recycle is necessary. One bar can last a great many washes and can potentially replace several bottles of liquid product.
This recipe is for one 50gm shampoo bar. Scales are the ideal measuring option for a recipe like this, however a pipette for liquid measures can be used in this case as quantities are so small.
Phase A
50gm sodium coco sulphate needles
2gm argan oil
1gm rosemary essential oil
.25gm liquid germall plus preservative
Phase B
1 level teaspoon agar agar powder
1gm glycerine
2 teaspoons boiling water
D & C colour powder (optional)
Lavendar Oil (optional)
1.Prepare your mould. This should be something you can press hard into and then release such as a bath bomb press. Cling film may be needed in case of sticking. If you don’t have such an item scone cutters may be used by placing cling film on your bench then the cutter.
2.Place phase A in a bowl and combine well
3.Place phase B in a separate bowl and work quickly to create a smooth paste. This will thicken dramatically so lumps and colour specks will need to be cleared before moving to the next step.
4. Add phase A to phase B and combine well with a gloved hand for best results. Do not overwork as you may start the needles foaming.
5. Pack firmly into your prepared mould and compress well before gently removing your moulding. Allow to dry for 24-48 hours before use.

I am hoping to trial making my first shampoo bar. Your recipe seems to be quite simple, although I appreciate you have done the hard yard for us in experimenting with the base product’s to make it work. I was wondering though if you need to melt the scs needles and also would the recipe work if I replaced Argan oil with castor oil using the same ratio?
