Learn hair loss One of the primary cause of hair loss is a high amount of the male hormone, dihydrotestosterone (DHT) within the hair follicle. DHT is produced from testosterone in the prostate, various adrenal glands, and the scalp. After a period of time, an over abundance of DHT causes the hair follicle to degrade and shortens the active phase of the hair. Another factor that has been linked to hair loss is the amount of sebum in the scalp. Sebum contains a high amount of DHT, and clogs pores in the scalp, both of which cause the malnutrition of the hair root. The amount of sebum in balding hair is related to the amount of oil in the hair. Meanwhile most doctors agree that frequent shampooing is advised in hair loss cases with oily scalps. For women, hair loss is different. There is no set pattern for womens androgenic hair loss, which like MPB, occurs in the overwhelming majority of cases. Women can suffer from alopecia totalis and alopecia universalis just like men. Women can experience patch baldness for the same reasons as men (stress, poor nutrition, etc.), as well as due to hormonal changes from pregnancy and certain eating disorders. However, like men, the hair will generally grow back. The chief difference in womens androgenic hair loss from mens (both are hormone related) is that women tend to experience thinning that occurs in no particular pattern or part of the scalp. Unlike men, the scalp may not actually be totally denuded of hair, just thin to the point where the scalp is visible. Like men, however, the resulting hair loss is generally irreversible. The effectiveness of medications used to treat alopecia depends on the cause of hair loss, extent of the loss and individual response. Generally, treatment is less effective for more extensive cases of hair loss. New hair resulting from minoxidil use may be thinner and shorter than previous hair. But there can be enough regrowth for some people to hide their bald spots and have it blend with existing hair. New hair stops growing soon after you discontinue the use of minoxidil. If you experience minimal results within six months, your doctor may recommend discontinuing use. Side effects can include irritation of the scalp. Finasteride (Propecia). This prescription medication to treat male-pattern baldness is taken daily in pill form. Many people taking finasteride experience a slowing of hair loss, and some may show some new hair growth. Positive results may take several months. Finasteride works by inhibiting the conversion of testosterone into dihydrotestosterone (DHT), a hormone that shrinks hair follicles and is an important factor in male hair loss. Rare side effects of finasteride include diminished sex drive and sexual function. As with minoxidil, the benefits of finasteride stop if you stop using it.
Hair care tips and advises Many people (wrongly) will drop a handful of shampoo on their head and then rinse it off. Shampoo must be worked through all of your hair, as well as the scalp and hairline. Did you notice that when you shampoo your hair the amount of lather often varies? Usually, the more lather you have, the less buildup you have on your hair. It's also important to fully rinse out the shampoo to eliminate any residual detergents--they can damage the hair shaft and scalp. Frequently shampooing can dry out your hair and, therefore, must be followed by the use of a moisturizing conditioner. It is very important to work the conditioner through all of your hair and leave it in for three to five minutes. Again, many people misapply and misuse conditioner by not working it through to the ends of the hair and not leaving it on long enough. Blond hair may turn yellow, fade or become dull due to UV exposure. Even natural brunette hair tends to develop reddish hues from sun exposure due to oxidation of melanin pigments.
Hair growth Hair is composed of Keratin, a special protein that also produces our fingernails and toenails the nails and forms the protective outer layer of our skin. Each strand of hair consists of three concentric layers, the cuticle, the cortex and the medulla. The innermost layer of hair is called the medulla and reflects light giving hair the various color tones it has. That's why hair color looks a lot different in sunlight than it does in the shade. Hair that is dark and very visible is known as Terminal hair. Terminal hair is the hair that we refer to when talk about hair. Whether a hair is a fine vellus hair or a thick dark hair depends entirely on the follicle that is producing the hair. In balding men thick terminal hair is often replaced by fine vellus hair. This is a result of the hair producing equipment, the follicle, suffering physical damage and being unable to produce terminal hair. About 90 percent of the hair on a person's scalp is growing at any one time. The growth phase lasts between two and six years. Ten percent of the hair is in a resting phase that lasts two to three months. At the end of its resting stage, the hair is shed. When a hair is shed, a new hair from the same follicle replaces it and the grow-ing cycle starts again.
Definition interpretingAlopecia Areata
- Alopecia areata is a hair loss condition which usually affects the scalp. It can, however, sometimes affect other areas of the body.
Hair loss
- A progressive, diffuse loss of scalp hair in men that begins in the twenties or early thirties, depends on the presence of the androgenic hormone testosterone, and is caused by a combination of genetic and hormonal factors. Also called androgenetic alopecia.
Hair transplantation
- Hair transplantation is a surgical procedure used to treat baldness or hair loss (alopecia). Typically, tiny patches of scalp are removed from the back and sides of the head and implanted in the bald spots in the front and top of the head.
Protein
- Important building blocks of the body, composed of amino acids, involved in the formation of body structures and controlling the basic functions of the human body.
- Complex organic molecules made up of amino acids. Proteins are basic components of all living cells and are therefore among the principal substances that make up the body.
Ringworm
- The term "ringworm" refers to fungal infections that are on the surface of the skin. The early belief was that the infection was due to a worm, which it is not, although the name has stuck. Some of these fungi produce round spots, but many do not.
Thyroid
- A gland in the throat that produces hormones that regulate growth and metabolism.
- A large gland in the neck that functions in the endocrine system. The thyroid secretes hormones that regulate growth and metabolism.
Alopecia
- A hair loss, baldness, and epilation.
- Alopecia, also called hair loss, baldness, and epilation, is a common side effect of chemotherapy and radiation therapy.
Baldness
- A progressive, diffuse loss of scalp hair in men that begins in the twenties or early thirties, depends on the presence of the androgenic hormone testosterone, and is caused by a combination of genetic and hormonal factors. Also called androgenetic alopecia.
Biotin
Follicles
- A follicle (from the Latin folliculus) is a term to describe a small spherical group of cells containing a cavity.
Grafts
- To transplant or implant surgically into a bodily part to replace a damaged part or compensate for a defect.
Hormone
- A substance, usually a peptide or steroid, produced by one tissue and conveyed by the bloodstream to another to effect physiological activity, such as growth or metabolism.
Scalp
- The skin covering the top of the human head with its attached hair.
Stress
- Importance, significance, or emphasis placed on something.
- The relative force with which a sound or syllable is spoken.
- Accent or a mark representing such emphasis or force.
- An applied force or system of forces that tends to strain or deform a body.
- A mentally or emotionally disruptive or upsetting condition occurring in response to adverse external influences and capable of affecting physical health, usually characterized by increased heart rate, a rise in blood pressure, muscular tension, irritability, and depression.
- A state of extreme difficulty, pressure, or strain.
- A physical and psychological response that results from being exposed to a demand or pressure.
Testosterone
- A white crystalline steroid hormone, C19H28O2, produced primarily in the testes and responsible for the development and maintenance of male secondary sex characteristics. It is also produced synthetically for use in medical treatment.
