Thoroughly wash the roots and remove any dirt. Cut the shoots and roots into small pieces and put them into a food processor. Add the voska and mix them thoroughly. Let the mixture steep for 24 hours to allow the alcohol to solubilise the active components of the plant. Then filter through a coffee filter or clean mousseline towel. Add the rose water and fill into a spray bottle.
The tonic will keep for 3-4 months without any trouble.
Nettle Hair Tonic No. 2 (vinegar-based)
If you want to avoid using alcohol in your tonic, try this recipe instead.
- 10-15 fresh growing tips of young plants
- 150 g fresh nettle roots
- 500 ml water
- 250 ml white wine vinegar
Thoroughly wash the roots and remove any dirt. Chop the roots and shoots and put them in a pot. Pour the water and vinegar over them and let steep overnight. Bring to the boil the next day, and let the hot mixture steep a further 30 minutes. Once cooled, filter through a coffee filter or mousseline towel and fill into a clean spray bottle.
Due to the vinegar, this tonic has a stronger smell than the alcohol-based version. It will keep in the fridge for about 4 weeks.
How to you use the tonic
Apply to the scalp directly after washing your hair, while the hair is still wet, and gently massage into the scalp with your fingers.
Both tonics work best for dark hair – light blonde hair might get darkened slightly by the nettle tonic.
How long does the tonic keep?
The alcohol-based tonic will keep for 3-4 months without any trouble. We’ve always used up our supply by this time, so we’re not sure how long it will keep after that.
The vinegar-based tonic will keep fresh for about 4 weeks in the fridge.
