1 cup Nettle
1 cup Spearmint
1 cup Rosemary
and for a rich chestnut appearance cloves
Place soapwort in a glass or enameled pan pour over it 1-1 1/2 cups water. Bring this to a boil and lower the heat and simmer for 10 minutes. Cover it and let it steep until cool strain it into a bottle that closes tightly. Take the three other herbs and cloves and place them in a glass or enamel pan and pour 2 cups of water over them. Simmer them after bringing to a boil the same way. Let them steep for at least 2 hours, then strain. The liquid left will be very dark brown. Mix this with the soapwort mixture at a 1:1 combination.
When you add the nettle, rosemary, spearmint and cloves let it infuse for at least 60 minutes but overnight is better. In the morning you can add a couple drops of your favorite Essential Oil to add fragrance. Pour into bottles. Shake well before using. This won't give you a head full of suds as commercial ones will but the cleansing is undeniable.
This blend is essentially for brunettes. If you have lighter hair, substitute chamomile for the rosemary and lemon or lemongrass for the cloves. If you want deeper conditioning you can add fennel to it as well.
