Why does hair become brittle? What s wrong with brittle hair

1. Dieting too violently. Dr. Rena Davidson, an endocrinologist in London, says that excessive dieting**, especially a low-carb diet, can lead to glucose deficiency, which can lead to hair loss.

2. Iron deficiency. According to Dr. Davidson, iron deficiency is the number one cause of hair loss in premenopausal women. Iron-rich foods include: red meat, egg yolks, green leafy vegetables, etc. Vitamin C supplementation also aids in iron absorption.

3. Obesity. Gaino Busell, an expert at the British Dietetic Association, said obesity increases the risk of metabolic syndrome, especially the precursor of type 2 diabetes, leading to abnormal insulin levels. Too high insulin levels can lead to an increase in androgens in a woman's body, increasing the chance of hair loss.

4. High pressure. High levels of stress can lead to telogen effluvium. This causes hair to fall out prematurely into telogen phase. Long-term stress can also overload the immune system, causing white blood cells to attack hair follicles, which can also lead to alopecia areata.

Hair lack of moisture, just like ** lack of water will dry and crack, you had better wash your hair every time, with a film to care, the effect is very good, the most important thing is not to rinse too clean when rinsing the film after care, so that the film remains on the hair, which can play a role in replenishing moisture and protecting the hair.

"There are two types of causes of hair breakage: internal and external. The internal cause is caused by the congenital calcium deficiency disease of the hair itself, or the abnormal thyroid function, which is also the reason why the hair is easy to break, and there are many external factors, such as: 1. Perming and dyeing hair.

Frequent perming of hair or hair exposure to the sun; 2. Unreasonable hair blowing. The hair is very wet after washing, and in the high temperature of the hair dryer at this time, the water in the hair boils and produces bubbles, which also makes the hair easy to break; 3. It is best not to use shampoo that usually washes hair, because it is easy to hurt the hair, resulting in the situation that the hair cannot be combed and will be broken after combing; Fourth, staying up late for a long time, fatigue, and mental pressure lead to endocrine disorders, and it is easy to make hair softer, thinner, dry, and easy to break. ”

What are the usual causes of fragile hair? This aspect is related to our lifestyle habits, such as improper hair washing, using low-quality shampoo and conditioner, or wrong combing, long-term dyeing and perming, and not paying attention to hair sun protection in summer are all causes of fragile hair.

In addition, hair breakage may also be caused by insufficient nutrients, when the nutrients required by the hair are not enough to supply the normal needs of the hair, resulting in a lack of nutrients in the hair, it will be easy to break the hair.

In addition, some congenital causes may also cause hair to be brittle and easy to break, such as congenital hair is very thin, so the chance of hair breakage will be relatively higher.
