What causes hair loss?

There are many causes of hair loss ranging from poor blood circulation to environmental pollutants. However, the primary cause of baldness is an excess of the chemical DHT on the scalp. Nisim Biofactors' products are among the few to face clinical studies and emerge with scientific proof of success in overcoming hair loss and baldness by neutralizing DHT though the use of natural Saw Palmetto (also known as Serenoa Serrulata). In fact, 85.7% of men who participated in this study saw hair regrow even after 2-5 years of baldness. The average increase in hairs was 193.7% in those who showed significant regrowth.

The science behind hair growth is explained in detail at About Hair Growth. For those who want the short answer, heredity in men plays a major role, resulting in receding hair lines and balding scalp. A male hormone called dehydrotestosterone influences hereditary factors in androgenetic alopecia (or male pattern baldness). Changes in women's health, including hormonal changes that occur in menopause, are mainly responsible for female hair loss and thinning. Frequent shampooing, poor circulation, wearing hats or any other personal habits are not factors that cause hair loss. Accidents, burns, disease and a few medical treatments can also trigger hair loss.  more

There is much debate on this topic. While the link between certain forms of hair loss and the immune system is well-accepted, there is also evidence for a connection between the immune system and pattern loss (androgenic or androgenetic Alopecia). In line with this, it appears that male hormones--especially DHT--trigger an autoimmune response in pattern loss, initiating an attack on the hair follicle that can be observed microscopically. This results in destructive inflammation that gradually destroys the follicle's ability to produce terminal hair. The reason for this could be that androgens somehow alter the follicle, causing it to be labeled as a foreign body. A possibly related factor is that elevated androgens also trigger increased sebum (oil) production, which can favor an excessive microbial and parasitic population, also leading to inflammation. In any case, hair progressively miniaturizes under the withering autoimmune attack, so that with each successive growth cycle it ...  more

The most common cause of hair loss for both men and women is heredity. Either or both parents can pass on the gene that causes hair loss. Typically, men are more susceptible to hereditary loss of hair because of testosterone. When broken down to dihydrotestosterone, it acts as a catalyst to activate the hair loss gene. Both men and women are susceptible to this condition, which has been labeled as androgenetic alopecia. This means hereditary loss of hair with androgens (dihydrotestosterone). Other reasons for hair loss may be underlying medical or hormonal problems, medications, excessive weight loss, chemotherapy, or radiation. Also, traumatic injuries, scarring scalp conditions, or burns to the scalp can cause permanent hair loss.  more

The most common cause of hair loss is inheritance. Men and women inherit the gene for hair loss from either or both parents. Men are most commonly affected by the inherited gene as the hormone, testosterone, activates the genetic program causing loss of hair follicles. Currently there is no known method of stopping this type of hair loss. The age of onset, extent, and rate of hair loss varies from person to person. Severe illness, malnutrition, or vitamin deficiency can accelerate this process. When applied incorrectly, permanent hair color and chemical relaxers damage the hair and follicle to the extent that hair loss can be permanent. Causes of hair loss do not include wearing a hat, excessive shampooing, lack of blood flow, or clogged pores.  more

There are several different types of hair loss such as alopecia areata ( temporary hair loss in a coin shaped patch ), telogen effluvium ( temporary hair loss as a result of stress on the system such as a severe illness or certain types of medication ) and androgenetic alopecia ( male pattern hair loss ). Androgenetic Alopecia is by far the most common form of hair loss. This condition generally becomes evident in the 20's or early 30's by a gradual loss of hair on the top of the head and in the angles at the front hairline. The exact mechanisms associated with this type of hair loss are still unknown but without doubt inherited factors and the effect of androgens ( male sex hormones ) are mostly responsible.

Hair loss, or alopecia, is a common disorder and can be due to many causes. Human hair undergoes phases of growth and rest during their life span. The growth phase is called anagen; 80% of the scalp hair is in this phase at any point of time. 20% of the hair is in the sleeping phase called telogen. It has been estimated that the scalp normally contains about 100,000hairs. Therefore, the average number of hairs that can be lost in a day is about 100. Hair loss can be of several different types, including alopecia areata (temporary hair loss in a coin-shaped patch), telogenef fluvium (temporary hair loss secondary to a stressor on the system), and androgenetic alopecia (male-pattern hair loss). The most common, male pattern hair loss is seen during the 20s or early 30s by gradual loss of hair, chiefly on the top of the head and in the angles at the frontal hairline. It is thought to be due to the male hormone combined with genetic factors.

Alopecia that is widely known as hair loss represents a rather common disorder, which can be caused by different factors. There are two stages that hair undergoes: growth (anagen) and sleeping (telogen). 80% of the hair is always in the growing phase, and 20% - is in the sleeping period. Normal average of hairs is around 100,000. The normal number of every day hair loss is about 100 hairs. The male pattern of hair loss represents a gradual loss of hair in the 20s or early 30s; the zones of hair loss are the angles at the frontal hairline and the top of the head. The reason of male hair loss is the combination of male hormones and genetic factors.  more
