Hair is a very thin filament that arises from the skin of humans and various animals, especially in species that belong to the group of mammals. In the case of people, hair is used as a synonym for hair .
Hairs are born in hair follicles , where their roots are located. They are made up of a keratin fiber and grow upward, so that the stem protrudes from the surface of the epidermis .
It is important to mention that hair is present on most of the body surface. It is estimated that an adult has about five million hairs , of which one million of them are in the head area.
Among the functions that hair performs, the conservation of body heat stands out. Those that are located on the scalp also provide protection against impacts , while those that form the eyebrows prevent sweat from the forehead from entering the eyes. The hairs of the eyelashes , meanwhile, protect the eyes from dust and excess light.
Hair has different characteristics depending on each individual. According to melanin , it can be blonde , brown , black , red , gray or white , for example. Regarding its structure, on the other hand, it can be curly , wavy or straight . Furthermore, hairs are differentiated according to whether they are oily , dry , mixed or normal .
Beyond its anatomical importance, hair has an aesthetic role. To care for and beautify it, a large portion of society usually goes to establishments known as hair salons , where different experts are in charge of washing, cutting, combing and dyeing it.
But hair care is one of the most expensive tasks on a monetary level, largely because we must carry it out very consistently. Hair grows constantly, especially during spring, and this is usually counterproductive for treatments that seek to hide gray hair or change its shape (straightening or curling it, for example).
Another reason for the economic impact of hair care is the price of the products that many people believe are necessary, such as shampoo, cream rinse, dye , hair ampoules and more. But the secret to having healthy hair is found in personal hygiene , particularly in the use of a comb and brush: combing our hair serves much more than just shaping the hair, since it eliminates hair that is in the process of falling out, removes those that They have already come off and stimulates blood circulation in the scalp.
Combing our hair is one of the most productive activities to keep our hair healthy, especially because it allows it to continue growing without interruptions. The most appropriate times are before showering, to enhance the effects of the shampoo and prevent it from getting tangled when wet, and before going to sleep.
The temperature of the water is also an important factor in caring for your hair. It is recommended to use cold water in the last rinse to stimulate blood circulation and close the cuticle, thereby increasing its shine. The beginning of washing, however, should be done with warm water, but never hot, because this can damage the hair.
On the other hand, the shampoo should be applied only to the roots . The correct use consists of activating it on your hands, rubbing them for a few seconds, then passing it over the scalp and letting it sit for a couple of minutes before rinsing. Only when we put ourselves under the water does the shampoo naturally descend to the rest of the hair and clean it, without the need to exercise any type of movement with our hands.
