CAMPAIGN OBJECTIVE (MORE INFO): Great hair starts below the surface Most believe that the root of the hair strand is what you see just above the scalp. But like with most things in life, what lies beneath the surface will astonish you. Your hair has actually been growing underneath the skin for a full two weeks before we’re even graced with its presence. Hence we like to think of caring for the scalp as akin to gardening: if you nourish the soil, what grows out of it should flourish.
