Hair Loss Causes and Treatments


Hair is an aggregate of filaments that cover the human head, the coat of most mammals, and even the surface of plants. It is a very tiny measure of the body. Hair is a recurrent theme throughout cultures and religions. There are numerous different types of hair and many reasons why you might experience a loss of hair. Here are some of the reasons. Listed below are some common causes and treatments for hair loss. Read on to learn about more common causes.

The shaft of the hair is made of two or three layers, called the cuticle, cortex, and medulla. The outermost layer, the cuticle, is composed of flattened cells that overlap. These cells are what give hair its texture. Hair with the “S” pattern is often smooth, straight, or curly. Generally, thick strands are harder and feel more like a string. This type of hair can be extremely resistant to styling, making it difficult for a stylist to create the look you desire.

Certain genetic variations influence hair color and shape. For instance, people with fair skin often have blonde hair, while people with darker skin usually have darker brown or black hair. Hair color also has something to do with follicles, which determine the thickness, coarseness, and fineness of the hair. These factors can cause hair to appear wavy or curly, and thinning or thicker than you might prefer. Aside from genetics, there are many factors influencing the shape of your hair.

The reason humans have hair is because it serves many different functions. In addition to providing insulation, it also serves as a barrier against the sun, dust, and other debris. The hair around the eyelids protects the eyes from dust and sweat. Eyelashes, on the other hand, protect the eyes from water and dust, and eyebrows serve as sensory organs. They are incredibly sensitive to air movement. They also provide protection against cold. This is why a lot of mammals have hair.

The follicle is the origin of hair. Hair follicles are a tube-like structure under the skin’s surface. Inside the follicle, a sebaceous gland produces sebum, a lipid-rich substance that protects hair while moisturizing the skin. The hair follicle is attached to a layer of mitotically active basal cells called a sebaceous gland. Hair cells reproduce here and are pushed upwards to form strands.

The earliest known hair on human beings was lanugo. It started growing in the third or fourth month of the fetal life and was shed shortly after birth. This slender hair is also called down hair or vellus. It covers every part of the body except the palms and the undersides of the toes and fingers. The first hairs that humans have were shed at around 299 ma, so hair growth on this body part was most likely an early adaptation for survival.

Hair loss can be triggered by a variety of medical conditions. Inflammation of the hair follicles, referred to as folliculitis, can lead to hair loss. Other common causes of hair loss include acne and an excess of testosterone, which leads to hirsutism. Genetic testing for paternity or DNA can be done from hair follicles. Hair analysis may be beneficial for determining a person’s risk of a certain disease.
