I didn't know pillow mists existed, but I found out about them when a close friend bought one for me as a gift. If I spray it on my pillow before bed, the scent lingers in my hair until lunchtime. The scent is phytoncide, so it effectively masks scalp odor; it's a truly amazing product. Since it contains cypress water, spraying it on the pillow sterilizes it, and I heard it also contains essential oils that aid in sleep. I highly recommend this pillow mist; it kills not just two birds with one stone, but three!
