Other names: Hair depigmentation

The dark color of some structures of the body caused by the pigment melanin. From a development point of view comes from the cells that it consists of the basics of the nervous system, but most of these cells, melanocytes, discover the skin. They are contained in deeper layers of the skin and contain granules of dark dye. The dye from the skin of the scalp is transferred to the hair, to a degree dependent on our genetic dispositions. In old age, the pigment in the hair replaced by air bubbles,which gives the hair a typical gray to white in appearance. If you suddenly appear precincts lighter hair may be a problem with the formation of skin pigment melanin.

More often it happens that some hair turn gray suddenly, for example due to physical stress (severe illness, pregnancy) or excessive periods of mental stress.

It is the melanocytes that form on the skin cancers, forming in areas of freckles or moles. Failure their functions would be for us to be warned and in any case it is better to contact your doctor.

Blond hair, however, are likely to be trivial matters, such as “bleached” hair in the sun, the hair really can not be lightened across the board, but in the sources.
