In a large pot (like a Dutch oven), bring 6 cups of water to a rolling boil.  Add the dried chamomile flowers to the pot, stir, then remove from heat.  Let sit until just warm, about 20 minutes.  Strain the tea into a plastic pitcher. Rinse the large pot and place it in a bathtub.

Have an old towel nearby. Position your head over the pot.  Pour the tea from the pitcher through your hair, catching the tea in the pot beneath.  Repeat until hair is completely soaked.  Squeeze out excess tea so that your head is not dripping too much.  Place the towel over your shoulders to catch any tea.  Return the remaining tea from the pot back to the pitcher.  Blow dry your hair until it is dry again.

Repeat step 2 twice more, soaking the hair, drying, then soaking and drying again.  When finished, leave hair unwashed and without product for 12 to 24 hours, then wash and style hair as usual.
