This is a lovely, gentle shampoo that lathers and cleans the hair very well. It also rinses off easily without leaving any residue. The base for this shampoo is made from olive oil castile soap, which can be bought from a health food store but do be aware of imitations.
1 tablespoon dried sage leaves for dark hair or
1/4 cup dried chamomile flowers for fair hair
1 tablespoon dried peppermint leaves
2 tablespoons dried rosemary leaves
1 tablespoon stinging nettle leaves
1 cinnamon stick or vanilla pod (optional)
550 ml distilled water
3 drops peppermint essential oil
50 ml vodka
50 gram castile soap, grated
Place the dried herbs in to a heavy based saucepan (not aluminium or copper), add the water and bring to the boil. Reduce the heat and let the mixture simmer for around ten minutes. Remove from the stove, cover and steep for thirty minutes. Using muslin strain the mixture in to a bowl making sure you squeeze all the liquid from the herbs. Pour the liquid in to a clean saucepan and add the castile soap. Simmer and stir every few minutes until the soap completely dissolves then remove from the stove and allow it to cool; it should be the consistency of thin cream. Using a dropper add the peppermint oil to the vodka and stir in to the herb and soap mixture. Pour the shampoo in to a jar, cap it and let it stand for four days before using.
You can also use lavender or eucalyptus essential oils instead of the peppermint oil.
