If your scalp is...
CONGESTED: Try a deep-cleansing scalp scrub; exfoliating it thrice-weekly will help remove excessive, skin-clogging product buildup.
OILY: Consider switching to a scalp-specific shampoo to obliterate excess sebum; it's often the culprit behind that persistent patch of pimples that hangs out around your hairline and on your forehead.
TIGHT: Spritz on a soothing spray and use your fingertips to work it into your scalp a few times a week; regular stimulating tension-relief massages works wonders.
DRY: Apply a nourishing oil to your scalp twice a week; not only will it add much-needed moisture to a dehydrated dermis, it'll help encourage growth.
