If you have resolved to take some “me time” for the new year, indulging in a head and scalp treatment may be a good route to self-care. We all know the near-bliss of a good hair salon shampoo, during which the shampooer takes time to massage with fingers deftly working through your scalp. Imagine that experience multiplied in a relaxing one-hour session: Warm water pulses over your head, deep massage invigorates and loosens product buildup, and dead skin cells are eliminated for the ultimate pampering experience.
