Human hair is made up of a protein called keratin. Though the majority of your hair is dead, the one place it's alive is at the scalp. The dermal papilla is found directly under the surface of the scalp in a tube-like chamber of the hair follicle and is made up of many cells that are fed by the bloodstream into your skin. Scalp treatments are a big factor in keeping a healthy scalp, and my natural essential oil treatments help regulate the dermal papilla.
