Many men and some women complain of having a bad smell on their scalp. It can be a very frustrating issue. But, above all, it can indicate an even more severe problem that is known as seborrhea. It consists on the excessive production of capillary fat that triggers and accelerates hair loss. It is important to understand the characteristics of this kind of problem in order to apply an adequate treatment.
A functional disorder that affects many aspects of daily life
Seborrhea is a functional disorder that affects the sebaceous glands which tend to produce a hyper-secretion of sebum. This problem has been identified as a type of dermatitis as explained at http://www.webmd.com/skin-problems-and-treatments/seborrheic-dermatitis-medref. This chronic condition affects people of both genres and consists on the emergence of scales, pruritus and erythema on the affected area. It can be accompanied by the excessive generation of fat in some cases and extreme dryness in others.
However, seborrhea is generally related to the excessive secretion of fat. It really is an important aesthetic and dermatological problem, since it generates inflammation and itching. This condition gives hair a greasy, shiny and heavy appearance that makes it difficult to comb it and to keep it neat. The sebum produced by the scalp is altered once it comes into contact with air. It oxidizes and therefore, it acquires an unpleasant odor.
Specialists point out that this disorder is intimately linked to dandruff which is accountable for desquamation or dropping of dead skin crusts. Such factor activates and accelerates a condition known as Seborrheic alopecia as excessive fat drowns the hair follicle. Additionally, it stimulates the formation of dihydrotestosterone (DHT), a substance that has been found responsible for baldness.
Conditioning factors that trigger the emergence of this issue
Scientific studies have revealed that people affected by this disorder have certain predisposition. However, other factors such as stress and unhealthy habits can contribute to the excessive production of sebum.
A diet without an adequate balance of basic nutrients is one of the most frequent causes for the malfunctioning of sebaceous glands. Elements like animal fats, chocolate, cakes and stimulants such as alcohol, coffee and nicotine must be avoided at all times.
Hormonal activity has also a great incidence on the emergence of this disorder. Seborrhea usually appears after puberty and in adulthood, that is, when the activity of the sexual glands is more intense. Androgens such as testosterone are in charge of regulating the production of fat in the skin. They also play a decisive role on the weakening of hair follicles.
Sebaceous secretion is also regulated by a sector of the Nervous System known as neuro-vegetative which is vulnerable to alterations like those produced by stress or anxiety. Consequently, all psychoneurotic pathologies, such as fear and emotional disturbances affect the performance of follicles triggering seborrhea and hair loss.
Many people think that if they suffer from excessive fat production, it is best to resort to resources like a shampoo with an aggressive formula. However, such action generates a rebound effect, that is, the sebaceous secretion is increased. Other products that may cause a negative effect are hair sprays and dyes.
