What are woolen hair?

In medical terminology, woolen hair relates to several rare conditions where anomalies in the structure of the scalp causes the growth of fragile, very firmly twisted hair. The three most common forms are: woolen hair Nevus, a condition where eccentric hair grows in one or clearly defined area of ​​the scalp except enemy hair; hereditary woolen hair, where hair is present mainly in childhood and childhood; And familial woolen hair that is present from birth and are often associated with abnormalities of skin and heart. These conditions are congenital, which means that they are present since birth and occur only in people of Caucasian origin. In most people, curls in childhood are more noticeable than maturity. There are no medical treatment, although the stains of curly hair in woolen hair can not be surgically cut.

Symptoms include very tight curls that have a diameter of more than 0.5 cm) and tend to join, so the hair di.ficult for brushing or nailenu. The hair is also often short, because it is so fragile that the hair shafts tears before they get into a very long. It is recommended to avoid any harsh hair treatment such as bleaching, coloring or straightening when it has this condition.

This is the skin condition, which means it includes the surface of the body, including hair, skin and nails. Sometimes it is associated with other skin conditions and other physical abnormalities. For example, people with woolen hair sometimes do not suffer from skin lesions and unusual development of bones and teeth. Naxos syndrome, a form of familial woolen hair, is associated with a form of heart disease that affects the right chamber of heart muscle. People with this syndrome also often have skin abnormalities called keratosis on the scalp, palms and feet of the legs.

Scientists are not completely undestandian genetics of all types of this condition and have not found irresponsible for a particular gene. Hereditary woolen flapSY runs in families and is a dominant feature, which means that the child will have eccentric hair, even if the genetic property is transmitted only by one of the parents. Family woolen hair seems to be a recessive feature, which means that it will only be shown if it is inherited from both parents. Genetic anomalies causing Naxos syndrome were identified, but genes responsible for woolen hair Nevus are still unknown.
