The importance of hair is self-evident. What causes hair loss?

As the name implies, hereditary alopecia is the phenomenon of the first generation of parents' hair loss. Due to genetic factors, the next generation will still lose hair. Generally speaking, men have more genetic characteristics than women. There is a joke called "My mom is bald and my dad is bald." That's what it means. Unfortunately, hair loss caused by this genetic factor is irreversible and the treatment is almost ineffective.

2. Mental factors lead to hair loss

Modern people have a fast pace of life, great pressure, anxiety and even depression. According to the authoritative investigation report, when people are in a state of anxiety, the body will release a hormone called cortisol.

For example, without cortisol, people can only be dumbfounded and at a loss when attacked by the enemy. But if at this time, the human body secretes this hormone and exerts it, it can make the body start to escape or launch a counterattack mode against the enemy. Without cortisol, the human body will not react to sudden danger or stress.

When people are under pressure for a long time, cortisol secretion will increase. Too much cortisol can lead to too much oil secretion, leading to hair loss, and sometimes "alopecia areata".

3. Dietary factors lead to hair loss

This kind of hair loss caused by diet usually occurs in obese people. When obese people lose weight, their nutrition intake is insufficient, which leads to hair malnutrition and hair loss over time. Another is that obese people have higher body fat content, which aggravates hair loss.

4. Wash and dye your hair too often

In the process of dyeing hair, a lot of heat will be generated, and most of the hair dyes are chemical substances, which will seriously damage the hair quality, and the hair will become fragile and easy to break off. Among them, most hair dyes contain a chemical called phenylenediamine, which is a colorant that must be used in hair dyes. This substance is very harmful to people's health, and everyone must remember it.

Through today's understanding, I have a general understanding of human hair loss. In daily life, only by taking care of your hair carefully can you avoid the trouble caused by hair loss.
