Do you know the top ten reasons for hair loss in summer?

Looking at the clumps of hair falling from their heads, many people become anxious: Why am I losing hair - why am I losing so much hair - there are many reasons for hair loss. Below we count the top ten reasons for hair loss in summer. In addition to common causes such as staying up late, irregular lifestyle, and mental stress, eating cold drinks, using air conditioning, and sunbathing can also cause hair loss.

1. Eating too many cold drinks

The latest research has found that if you consume too much ice cream and other cold drinks in the summer, it is mainly because the cold drinks will cause sudden contraction of the hair follicles, which is particularly bad for the hair follicles that need to sweat a lot to dissipate heat in the summer.

For girls who love cold drinks, this point is probably often overlooked, and it is also one of the important reasons for hair loss in summer. Therefore, one of the ways to maintain your hair in summer is not to drink too much cold drinks, but to drink more boiled water.

2. Air conditioning heating and cooling

More and more people are suffering from hair loss nowadays. In addition to common causes such as staying up late, irregular lifestyle, and high mental stress at work, the cold and warm air from air conditioners can also be one of the causes of hair loss.

In the summer, if your hair is exposed to dehumidification by air conditioners for a long time, the moisture in your hair will be gradually drained away, making your hair dry and brittle, leading to hair breakage and hair loss problems.

3. Direct exposure to the sun

Hair loss in summer is closely related to external environmental factors. The summer sun is strong, ultraviolet rays directly hit the head, and thermal radiation can cause strong stimulation to the human head skin, causing hair damage and loss. Therefore, in summer, you should protect your hair from sun damage just like you protect your skin from sun spots.

In summer, you should avoid sun exposure to your head and reduce activities in the sun. When going out, it is best to wear a sun hat or carry a parasol.

4. Braiding too tightly or combing your hair back

This one may be more relevant to women, but even men should know that wearing their hair in tight braids (like in Afro dreadlocks or cornrows) or pulling it back (like in a ponytail) can lead to hair loss — or traction alopecia, as it's medically known. This is due to long-term tension in the hair, which can cause the hair to gradually fall out, especially at the hairline.

5. Vitamin/mineral deficiency

Whether it's due to crash dieting, unbalanced nutrition or some genetic or physiological defect that causes a lack of certain nutrients, it can lead to hair loss. Hair loss is often caused by iron deficiency. Severe iron deficiency in the body can easily lead to iron deficiency anemia, which means the body does not have enough red blood cells. Red blood cells are very important to the human body because their function is to transport oxygen to every cell in the body and help these cells maintain normal function.

Deficiencies in other nutrients — such as B vitamins (especially B12) and protein — also commonly cause hair loss.

6. Swimming pool bleach

Swimming is a favorite sport in summer. However, the chlorine contained in the pool water can also damage the hair. Therefore, it is particularly important to wash and care for the hair after swimming.

7. Pressure

Severe physical stress (such as surgery) or severe psychological stress (such as a death in the family) can have strange effects on the body. Severe stress often puts the body into a state of shock, with various hormones and metabolites flooding the body. This can lead to telogen effluvium, the rapid hair loss we mentioned above. We understand the effects of acute stress on hair, but it's less clear how chronic or long-term stress affects hair loss.

8. Hypothyroidism

The thyroid gland is a small gland located at the front of the neck, below the voice box. It plays an important role in regulating the body's metabolism by releasing a variety of hormones. Hypothyroidism, which is low production of a certain hormone, is the most common cause of hair loss known as alopecia areata (which can affect the entire body, not just the head).

Hypothyroidism itself can be caused by birth abnormalities, autoimmune diseases, or surgical procedures including thyroidectomy.

9. Frequent inflammatory stimulation

If the scalp develops folliculitis, tinea versicolor or other furuncles, carbuncles, etc., the hair roots will become unstable and hair loss may occur easily. The climate is hot in summer and the human body sweats easily. In addition, there is a lot of dust and germs multiply quickly, making it difficult to clean the hair thoroughly. Once a skin disease occurs on the head, serious hair loss will occur.

Therefore, you should pay attention to the cleanliness of your hair and wash it frequently in summer. When washing your hair, you can rub your scalp with the fingertips of both hands. This can promote blood circulation in the head and protect your hair. However, do not scratch it with your nails to avoid scratching your scalp. When washing, you should thoroughly remove the residual detergent on your hair to avoid damaging your hair.

10. Trichotillomania

Trichotillomania is the habitual pulling of hair from the head or other parts of the body. While it's unclear whether trichotillomania should be classified as a habit or considered a compulsive disorder, the end result is the same.

Over time, alopecia areata will occur. If you break the habit, your hair will regrow, but long-term, excessive pulling and damage to your scalp can cause permanent hair loss in the affected areas.
