The best things can happen when you just start making stuff up.
Inspired by the herbal tea hair rinse line at Chagrin Valley Soap & Salve Co., I tried my hand at making my own. There wasn't a lot of method to my madness. Drawn by supposed qualities, I let sweet, earthy aromas & playful colors of flowering herbs lead me to grab whatever appealed to my senses & whatever my natural grocer happened to have stocked in bulk.
After using it, my curls were prettier & shinier, enlivened with more body than usual - practically a miracle in this desert.
0.4 oz dried lemon peel - 0.3 oz oat straw - 0.2 oz horsetail - 0.3 oz rose buds - 0.1 oz chamomile - 0.2 oz nettle - 0.2 oz calendula
Bring 1 to 2 cups of water to just below* boiling & pour over 3 - 4 tablespoons of tea mixture. Steep, covered, for 30 minutes. Strain leaves/buds & use tea water as a hair rinse after shampooing**. I like adding lemon juice. I leave it on my hair for a couple minutes, combing through it with a wide-tooth, before rinsing. Alternatively, you can leave it in instead of rinsing.
You can also infuse apple cider vinegar with the tea herbs for a few weeks, (strain) & use as a rinse. I have not tried this, since ACV is making my hair stringy lately.
*boiling water is damaging to herbs' properties
**I use natural shampoo bars from Chagrin Valley
I chose herbs suited for my naturally dry hair, leaning heavily on teas for adding body; I wanted to bring out my golden highlights, as well as some reds, too. Below I've listed other hair types & complementary herbal teas. Honestly, I wouldn't even bother with exact measurements; just let your intuition guide you to a few choices & start throwing them into a jar. Gently shake them up, steep, & rinse away.
