The Power of Hair

Hair serves as a biological advertisement, representing genetics and health. The power of hair has been the subject of many ancient myths. Rapunzel’s story is about the hair’s allure and connection. In Samson’s story, the man’s tresses provide him with mystical strength. Whatever way you wear it, your hair is a powerful advertisement. It can make you look good or make you feel bad, depending on how you wear it.


Hair has a great social significance for humans. Though hair grows on most of the body’s exterior surfaces, it is not possible to grow hair on the soles of the feet and palms of the hands. Most people choose to trim their hair in specific areas. Face, eyebrows, and ears are the most common areas to be trimmed. Other areas that require trimming or plucking include armpits, pubic region, and legs. A notable secondary sex characteristic of hair is the lack of it on females’ faces.

Human hair is made up of three layers – the cuticle, cortex, and medulla. The cuticle is a layered layer of cells that form the outer layer of the hair shaft. The cuticle is square and flat and adheres tightly to the cortex cells. This causes extensive overlapping, which facilitates the removal of dirt. The cuticle also has barrier functions against chemical and physical insults. Hence, it is important to take care of hair follicles, and keep them in optimal condition.

The hair shaft contains three layers. The innermost layer is called the medulla, while the middle layer is the cortex. It is the cortex that makes up the bulk of the hair shaft and contains much of the melanin that gives it its color. The outermost layer is the cuticle, which is a single layer of cells arranged in a scale-like arrangement. The cuticle is a barrier for the medulla and cortex.

The hair shaft is composed of three layers: the cuticle, the cortex, and the medulla. The cuticle cells are flat and square, and adhere tightly to the cortex cells. They move upward, causing extensive overlapping. The cuticle also contributes to follicular anchorage. The cuticle also serves as a barrier against chemical and physical insults. In addition, the cuticle reflects the underlying structure of the follicle.

The hair medulla is the center of the hair shaft. It is more visible on the head and shoulders than on the rest of the body. It contains structural proteins that are different from the other keratins in the skin. Additionally, it contains eosinophilic granules filled with amino acids, which eventually form internal coatings within mature cells. The follicle is essential for growth. Its parts include the head bulb and the upper and lower follicles.

The outer root sheath begins at the base of the epidermis and extends into the hair bulb. This sheath contains several types of stem cells that develop into specialized cells. These cells divide more often than any other type of cell in the body and affect hair growth and structure. These factors have an important impact on the way hair grows, whether it is straight or curly. A follicle may be a source of life and death for a person.
