The notion of repolarization is not part of the dictionary of the Royal Spanish Academy (RAE). Instead, the concept of Polarization: the act and result of polarizing.
The action of polarizing, on the other hand, is used in the physical with reference to the modification of a ray of light through reflection or refraction, making them unable to reflect or refract again in certain directions. Polarizing can also be about orienting something in two opposing directions or focusing on one thing.
All these ideas they can help us understand what repolarization refers to. This term is used, for example, to refer to a process that takes place in the heart.
The heart contracts when it is electrically stimulated through what is known as depolarization. This makes cells have a positive charge and positive upward motion is recorded on an EKG. Then the repolarization: the myocardial cells regain their negative charge.
The concept of repolarization, in short, is associated with the recovery of natural ionic charge by a cell. In the case of neurons, the electrical impulse can generate three kinds of answer: polarization, depolarization and repolarization.
The resting neuron has a negative charge on the inside and a positive charge on the outside. What depolarization does is invert that condition, while repolarization supposes the recovery of the original polarization.
It is known by the name of capillary repolarization when treatment of an intensive nature that aims to repair and hydrate hair that has been burned or damaged. To do this, a mixture of specific products that is easy to prepare is used, which provides the body with the necessary tools to restore its shine, softness and resistance to the hair.
It is important to note that capillary repolarization has immediate effects. On the other hand, its application should not be made more than once every thirty days unless the hair is in very bad condition. terms; in this case, it is recommended to do it every two weeks.
Who needs hair repolarization? In general, people who abuse dyeing, artificial drying and flat irons, among other treatments considered abrasive for the hair. Many people choose their own methods of repolarization, instead of going to a beauty salon, since this carries more than one advantage, such as the lower price, greater control over the products to be used (always having the option of choosing natural ones over industrial ones) and saving time.
The ingredients necessary to perform hair repolarization at home are easy to find, as they are sold in pharmacies, supermarkets, beauty stores and hairdressers. On the one hand we have the products chemicals: keratin, repolarizing treatment, silicone, collagen, oil (almond, olive or coconut); on the other, the utensils: a plastic or thermal cap, a cup, aluminum foil, a brush used to dye hair and an iron.
The steps are the following:
* wash your hair with a mild, salt-free product;
* Mix in the cup two tablespoons of keratin, two of repolarizing treatment, one of oil, two of collagen and two of silicone (these proportions are for long hair at shoulder blades);
* apply the mixture to damp hair, using the brush and working in sections;
* leave approximately 10 minutes while the plates of the iron are covered with the aluminum foil and it is heated to 180 degrees;
* apply heat to the hair for very short periods, since the objective is to seal the product, and not to remove moisture;
* wait half an hour and rinse hair with Water fresh or warm, without any additional product.
