Contrary to popular belief, shampoos are not reserved solely for cleaning hair. Shampoos specially formulated for bald heads remove excess sebum, impurities, and dead cells. By gently massaging the scalp during shampooing, you'll make it supple while restoring firmness.
A gentle scalp exfoliation once a week, preferably the day before shaving, helps prepare the skin for shaving by removing embedded dirt and promoting microcirculation.
