Each person has his own, individual characteristics of hair. Where does such an individual hair structure come from, and what makes them different? Scientists have conducted research in this area for a long time, and are ready to answer this and other questions related to the hair on the head and body. It turns out that the whole thing is the cross section of the hair.
It depends on the cross section whether the hair will be straight, or it will turn out to be curly. Features of this nuance should be considered separately.
Cross section of hair and its features
The hair of each person has an individual structure, but in general terms they have a similar structure. Hair grows from a bulb, it can have different lengths, but its body has a round or oval cross section in any case. If you make a cross section and consider the hair under an increase, you can see that its shape varies, and each person has a peculiar one. The hair can be perfectly round, slightly or completely oval, and have other specific features.
As a rule, the Asians and the inhabitants of the Middle East have hair that is perfectly round in cross section. They differ in rigidity, perfect evenness, do not need straightening. Their color is predominantly black, reddish or dark brown hair with such a section is also sometimes found.In representatives of the Negroid race, the hair in the section is the most flattened. These hairs are also usually black, but they are extremely curly, and it can be extremely difficult to straighten them for a long time. Small, tight curls - it is them that provides a flattened elongated section of the hair.
Features of hair in Europe and Russia
Europeans and residents of Russia usually do not have extreme indicators. It is difficult to find both a perfectly round and as flattened section of the hair as possible. The indicators are average, the shape is mainly oval, expressed to a greater or lesser extent. The more hair is flattened, the more prone it is to curls. Many Russians and Europeans curly their hair slightly, creating large, fluffy curls. This is ensured by just the averaged cross-sectional shape of the hair.
Interesting fact: It is in the European and Russian territories that the largest number of color variations of hair is observed. The shade of the hair slightly flattened in the cross section can be from dark blond to almost white.
It is also worth noting that Europeans and Russians are characterized by one interesting feature: hair can curl in childhood, and then straighten for natural reasons. Hair in children can be more flattened in cross section than in adults. Asians and Africans do not have such a feature.
Hair follicles, heredity and curls
Hair follicles are also largely responsible for the characteristics of the hair. Follicles are curved in shape, the hair of which in any case grows folded.Smooth hair grows from straight bulbs. It is also worth noting that the tendency to form curls or direct hair growth can be traced at the genetic level. Curls are a dominant gene, which is most often traced in the first-born. But there are other factors that determine the shape and type of hair. They are also worth keeping in mind.
Other factors responsible for the type and propensity of hair
The condition of the hair in many ways signals a state of health, especially true for women. After exposure to certain chemicals, as well as certain diseases, can cause curly hair to straighten. It is also worth noting that there are cosmetic procedures that ensure hair straightening or styling in curls. But they should not be abused - both short-term and long-term effect solutions of this kind can give a side effect, spoil the hair, and cause them to fall out.
Features of straight and curly hair
According to many people, curly hair is especially beautiful. But at the same time they are more fragile, require delicate care. Curly hair is subtle and sensitive, it is recommended to wash it with warm water, select suitable shampoos and masks, oils for care. Fortunately, on sale you can find a lot of tools to maintain a beautiful hairstyle. Drying such hair with a hairdryer is not recommended.
Hair straight from nature is more stable, it is easier to maintain it in good condition. They can be cut off, but the tips can be trimmed periodically to ensure their perfect condition.Medium hair, the most common among Russians and Europeans, also requires moderate care.
Thus, the hair is curled or have a straight shape due to the cross section. The closer it is to the right circle, the straighter the hair. Root bulbs, genetics and human health also play a role.
