There's a reason for shedding: 7 causes of abnormal hair loss

In nature, whatever reaches the end of its life withers and falls, making way for new things to take its place. Our hair is the same. From the explanation of Dr. Suwan Srithamma, Director-General of the Department of Medical Services, throughout a person's life we have about 80,000-1,200,000 hair strands, each growing about 0.35 mm longer per day and living 2-3 years before falling out. Normally, in a single day a person's hair falls out about 30-50 strands, but if our hair falls more than that it's considered abnormally heavy. If left for a long time it may cause thinning hair or premature baldness, so you should find the cause in order to find a way to prevent and treat it properly.

The causes of abnormally heavy hair fall are these 7, as follows.

1. Cause of hair fall: from heredity

In our body we have the DHT hormone, which is a type of male hormone but is found in both men and women. The DHT hormone controls hair shedding, and in some people's bodies this hormone acts especially strongly, making hair fall faster than normal, and when the roots produce new strands they're shorter and thinner than before. It mostly occurs at the forehead and crown, and in men symptoms often appear from age 20 onward, while in women symptoms often appear after menopause.

2. Cause of hair fall: from hair temporarily stopping growth

The body may face certain conditions that make hair stop growing and fall out before the end of its life, such as being in recovery after major surgery or childbirth, getting side effects from certain medicines, or being affected by stress. Generally this symptom occurs for 1-3 months and then returns to normal.

3. Cause of hair fall: pulling or plucking hair

Often found in children under psychological pressure, such as being pressured by family or studies. Some may pluck their hair for fun until it becomes a habit. Hair in heavily plucked areas becomes patchy and left as short stubble.

4. Cause of hair fall: from fungus

Some children may get a fungal infection or ringworm on the scalp, causing patchy hair fall, a red rash on the scalp, itching, flaking, or scabbing.

5. Cause of hair fall: from hairstyling

Curling, coloring, perming, straightening, blow-drying, as well as using various hair products, may make hair dry and damaged, brittle and breaking, or cause scalp inflammation from irritation, ultimately causing hair fall.

6. Cause of hair fall: from medicines and radiation

Using certain medicines has side effects that can cause hair fall, such as cancer drugs, anticoagulants, drugs for toxic goiter, contraceptives, gout-prevention drugs, etc., as well as radiation therapy for cancer.

7. Cause of hair fall: from certain diseases

Patients with SLE, as well as chronic diseases such as thyroid, syphilis, liver disease, kidney disease, etc., may also have hair fall and thinning.

In addition, there's patchy hair fall whose cause is still not clearly known, with hair falling in circular patches, from 1-2 patches up to more than 10 patches all over the scalp, but the scalp where the hair fell has no inflammation. Sometimes it even spreads to the eyebrows and eyelashes falling out. Some people have this condition for a year and then it heals naturally on its own, but for some it may recur.

Thyroid-related hair loss

For anyone with abnormally heavy hair fall, try to observe your symptoms to see what cause your hair fall is from, so we can treat the hair-fall problem appropriately. Importantly, don't forget to wash your hair to clean the hair and scalp regularly, and avoid every kind of behavior that harms the hair and scalp, whether pulling/plucking hair, scratching the scalp hard, using hair products with harsh chemicals, as well as dwelling on stress. But if you find the symptoms don't improve, you should promptly consult a specialist doctor immediately.
