If you have superdark hair and would like to give it more of a golden glow, sift through your bags of tea and find your favorite chamomile brew. Fill a large mug with boiling water, then steep a chamomile tea bag in it for 10 minutes. Once the tea has cooled, pour it over clean hair and let strands soak overnight. Rinse and feel free to repeat! Chamomile is one of the gentlest essential oils, so you can even use it on color-treated hair without fear of brassiness. Bonus: this ingredient has antidandruff properties.
