To make any hair mask more of a luxury for the senses and enhance the mask, keep small bottle of essential oils near the shower. After shampooing, shake a few drops of lavender, geranium, rosemary, anything you like into the palm of your hand and massage into hair under your regular mask or conditioner. Your hair will absorb the scent and smell great for days, and release a bit if scent if you sweat while running or whatever.
