Hair, naturally, has to fall. What matters is how much is considered a normal fall. It is estimated that up to one hundred hairs a day is considered a natural fall, although this varies depending on the volume of hair. You have to draw attention to it is if the hair loss is higher than usual. If the amount is increased, it may be necessary to consult a specialist in dermatology .

Hair loss occurs both physiological causes, such as hair loss after childbirth, or pathological causes, because of some diseases.

Most conditioners and softeners sold in the market are often not in principle present big problems because they are products that are already approved for routine use in hair. However, dyes and permanent fastening products and they can affect the hair, especially causing allergic reactions.

The hair is formed, among other components, by a protein called keratin that has a helical arrangement and in three dimensions. Irons, hair dryers and products used to fix the hair, such as permanent, may impact on the hair shaft and alter their tertiary structure, which is what gives volume to the hair; but do not necessarily lead to increased hair loss. The hair becomes weak and falls if the root is weakened, and this type of hair care processes and do not affect the result.

It should be noted that the queue can contribute to a decrease in capillary density. The long, large and heavy ponytail is a type of hairstyle that exerts a pull on the hair root as a result of their weight, especially at the hairline of hair on the forehead.

Furthermore, the use of perfumes and colognes may affect the appearance of hair altering their external appearance, brightness, feel, etc.. Although, it is unlikely that a colony or a cosmetic affects root due to the depth in which it is located.

 

What foods help prevent hair loss?

Should increase consumption of foods rich in essential amino acids, vitamins, iron, zinc and various trace elements, among others, to prevent hair loss. These are fruits, vegetables, meats, seafood and milk, which are rich in such nutrients.

In conclusion, it remembers that the hair root is well established in the thickness of the dermis and therefore, it is very difficult for a permanent, a dye, a cosmetic, a cologne or perfume you can injure.

Another thing is the tertiary structure, ie the hair shaft. This really is going to be damaged if not careful. Therefore it is very important to use, especially in women with very dry or rough hair softener or conditioner, because it serves to protect the three-dimensional structure of the hair.

 

Does stress affect hair loss?

Stress, anxiety, depression and everything that entails an emotional surge is associated with increased hair loss. Once the emotional balance is achieved, the hair loss is slowed and can return to regain a normal appearance.
