DIY Tea Spa:
Tea is a natural hair color booster that can function as a rinse to bring out highlights in dyed or undyed hair. Chamomile revitalizes golden highlights in blond hair, black tea perks up brunettes, and berry or red teas add oomph to auburn or red hair.
Prepare eight ounces, let it cool, then saturate your strands with the solution. Put on a shower cap and wait for 15 to 30 minutes, then rinse with water.
