Scalp Care

Encouraging a Healthy Scalp Environment

We cannot stress the importance of cultivating a healthy scalp environment for healthy hair care. Your scalp is the birthplace of your healthy hair care journey. In The Science of Black Hair book, we discuss the form and function of the scalp. Here’s a summary!

Functions of the Healthy Scalp Skin
The skin cells on the surface of the scalp naturally shed as new healthy scalp cells are formed. These scalp cells are shed as minute particles that are invisible to the naked eye. This process is so highly synchronized that it often goes undetected until the process is thrown out of sync. When the scalp skin cell replacement process is disrupted ,dandruff and other scalp issues arise.

The basic life of a cell, whether it be the hair cells replicating within the follicle itself, or the cells present on your scalp, involves several basic functions. All cells need a supply of water, nutrients from the blood stream, a favorable environmental temperature, and the ability to “respire” and eliminate waste. Frequent hydration through the process of shampooing and conditioning will help keep this process in good working order.

What is a healthy scalp?
Healthy scalps are those where the skin is toned, pliable, and stimulated. A toned and flexible scalp indicates a healthy network of connective tissue and nourishing blood vessels, and a pliable scalp skin allows for better circulation to the hair follicles. A healthy scalp is also a clean, stimulated scalp.
