Your scalp feels weirdly sensitive when you shampoo your hair.
Stress often leads to the release of neuropeptides and other natural chemicals in the skin, and that causes inflammation, explains Richard Fried, MD, PhD, a clinical psychologist and dermatologist with a private practice in Yardley, Pennsylvania. In some people, that inflammation erupts in angry pimples or a flare-up of rosacea. In others, the neuropeptides, which are part of our innate immune response, can cause blood vessels to constrict, making skin all over the face and head feel tight, tingly and overly sensitive. You've also probably been tensing your facial muscles for weeks (unconsciously bracing for a confrontation), so they're tired and slightly sore. Fried says the sensations should subside when you start to feel more relaxed.
