Is there any way to save your hairline, which has been losing its hair as soon as autumn sets in?
After autumn, many people find that their hair falls more severely. What is going on? Does hair loss also depend on the season? What is true hair loss? How much hair loss is normal per day? Today, a dermatologist teaches you how to “worry at the top of your head.”
There is a reason for hair loss in autumn
Judging from the number of patients with hair loss who visit daily dermatology clinics, there is no particularly clear seasonality for hair loss.
However, there was a study on scalp hair follicles of healthy people, and the results showed that among healthy people, the proportion of telogen hair reached a small peak throughout the year in July. This part of the hair in the telogen phase will fall off when the telogen phase ends (2-3 months later). According to the time, it happens to be autumn.
Therefore, some people’s hair loss worsens in autumn, which may be a normal physiological phenomenon.
Losing 100 hairs every day is nothing
Alopecia refers to the process and symptoms of hair loss. There are normal cycles of scalp hair follicles, including growth phase (2-8 years), catagen phase (2-8 weeks), telogen phase (2-3 months) and shedding phase. Therefore, a certain degree of hair loss is a normal physiological process.
The hair loss that we are concerned about daily usually refers to abnormal hair loss. There are different types of abnormal hair loss, such as alopecia areata, androgenetic alopecia, or telogen effluvium.
Is losing 100 hairs a day considered too much? According to the clinical grading scale of hair loss, the amount of hair loss is divided into 6 levels. Level 1 is 10 hairs/day, level 2 is 50 hairs/day, level 3 is 100 hairs/day, and level 4 is 200 hairs/day. Day, level 5 is 400 hairs/day, level 6 is 750 hairs/day. Hair loss of grades 1-3 is normal. If it reaches grade 4 or above, or even grade 5 or 6, it is considered to be excessive hair loss.
Therefore, if the average amount of hair loss per day is less than 100 strands, it is considered normal and there is no need to worry too much. If the average amount of hair loss per day exceeds 200 strands, you need to be aware that there may be excessive hair loss.
This is the main cause of hair loss
Different types of hair loss have different causes, among which androgenic alopecia has the highest incidence.
Androgenic alopecia is characterized by a slowly progressive pattern of hair loss. In men, hair loss occurs in the frontotemporal and crown areas of the head; in women, hair is significantly thinning near the midline of the head. The causes of androgenetic alopecia are multifaceted, and current research shows that genetic factors and androgens play a decisive role in the pathogenesis. Factors such as inflammation around the hair follicles, increased life pressure, tension, anxiety, poor lifestyle and eating habits can aggravate the symptoms of androgenic alopecia.
Telogen effluvium is primarily characterized by acute or chronic increased hair loss. There are many factors that are affected, including physiological factors, fever, stress, drugs, endocrine, organ dysfunction, hair cycle disorders, nutrition and local factors, etc.
COVID-19 infection is also an important cause of telogen effluvium, which may be caused by hypoxia, inflammation, metabolic abnormalities, drugs, etc. Post-COVID-19 hair loss generally occurs 1-2 months after infection. Hair loss generally lasts 2-3 months. It is usually self-limiting. After the inducement is eliminated, the hair will grow back. If the amount of hair loss is relatively large, it will be about It takes half a year to a year to restore the appearance.
