Like the rest of the body’s skin, the health of the scalp is impacted by intrinsic and extrinsic factors. Intrinsic might include medical conditions, diet and lifestyle, and extrinsic includes hair products and environmental elements, to name only a few. For instance, if the scalp is inflamed as a result of a medical condition or because the follicle is clogged with dead cells and bacteria, the hair may become weaker or grow thinner.
Similarly, the scalp ages much like the rest of the skin. It can lose tone and elasticity, and cell production may decline over time. As the scalp ages, the hair weakens. It is part of the life cycle of the hair follicle, but that lifespan can be extended when the same methods and ingredients for skin care are applied to the scalp.
Since the scalp is skin, it makes sense that many of the cosmeceuticals used to maintain skin health produce similar benefits when applied to the scalp and hair.
Understanding the hair follicle
Although overall skin structure is fairly continuous throughout the body, its characteristics vary slightly on the scalp. For instance, the scalp contains more hair follicles than anywhere else on the body; has some of the thickest skin on the body; and also holds numerous sebaceous glands.
The sheer number of sebaceous glands and follicles on the scalp alone points to the need to dedicate special treatment to this area. The sebaceous glands produce oil to protect the hair, but if oil builds up, the follicle may become clogged or dandruff may be produced. Dandruff is a result of bacteria trapped in the oil, which causes itching, inflammation and increased cell turnover. This is when flakes of dead skin become apparent.
