Honey & Olive Oil Hair Treatment: Take 1/2 cup honey and mix it with 1/4 cup olive oil. If needed, warm the mixture in a microwave for 15 seconds. Use your fingers to apply a small amount of the mixture on damp hair, working it through the strands, down to the ends. Cover your hair with a towel and leave the mixture on for 30 minutes. Shampoo well, rinse and dry as normal.
