What Causes Hair Thinning & How to Stop it?

Hair thinning or losing hair is a common matter for every human being. It may happen while combing the hair or while bathing. On an average every adult human loses 50 to 100 hairs per day. However, any loss beyond that limit may be a sign of any other problem. Hair thinning or regular hair loss has multiple potential reasons, including food habits, deficiency of minerals and vitamins, medications for some other illnesses, severe stress, pollution, and certain genetic factors. As per the statistics, almost one third of the population of the world is suffering from hair thinning and hair loss and both men and women are facing the problem equally. Even in some illnesses, medications or physical problems children may also face the problem of hair thinning and hair loss.

What Causes Hair Thinning?

What Causes Hair Thinning?

Experts are yet to fix up exact causes of hair thinning, but it is proved beyond doubt that the below mentioned factors have some sort of influence in hair fall or thinning–

  • Hereditary Problems
  • Certain Hormonal Changes
  • Certain illnesses
  • Poor Health habits
  • Medications against certain illnesses.

These primary causes of hair thinning requires a little bit of explanations –

  • Heredity Problems as a Cause of Hair Thinning: Hereditary condition is the most common reason of hair thinning due to loss of hair. Both male and female patterns of baldness are determined by the certain genes. It usually occurs progressively after a certain age. Thus heredity determines three aspects of hair fall – the age at which a person will begin to lose hair, the rate of hair fall, and the extent of baldness. Hair thinning due to hereditary reasons may begin as early as puberty.
  • Certain Hormonal Changes to Cause Hair Thinning: Hormonal Changes influence hair thinning and hair loss to a great extent. Experts have established the following links between some hormonal imbalances and hair loss and thinning –
    • Excess Estrogen: Excess estrogen in the body may cause loss and thinning of hair. In women, estrogen has several functions including longer hair life, but over secretion of this hormone causes sudden loss of hair.
    • Insulin Issues: Insulin is the controller of blood sugar level in human body. However, increasing insulin resistivity of the body may cause faster hair loss. Both males and females are affected by this problem. Experts have even established a close relationship between Androgenic Alopecia with female pattern baldness.
    • Testosterone Imbalance: Men carrying genes of male pattern baldness, inherit hair follicles that are oversensitive to hormone dihydrotestosterone (DHT). Once testosterone is changed into DHT, it shrinks the hair follicles on the scalp, resulting in shorter and finer or thinner hair. Eventually, hair growth stops altogether. In case of females too, over secretion of testosterone results into lower rate of hair growth on the scalp.
    • Low levels of Thyroid: Risk of both male and female patters of baldness increase due to low levels of Thyroid.
  • Certain Illnesses Responsible for Hair Thinning: There are certain illnesses that may cause mild to severe hair thinning and hair loss –
    • Thyroid Problems: Both due to hyperthyroidism and hypothyroidism hair can become thin and fall abundantly.
    • Cancer: In different types of cancer like Hodgkin’s disease and liver cancer, hair may become thin and fall drastically.
    • Lupus Disease: In this disease, hairs become brittle and fall in patches making them thin.
    • Other Diseases: In other diseases like Muscular Dystrophy, SarcoidosisHIV and Syphilis etc., hair thinning and loss may be mild to severe.
  • Hair Thinning Caused Due to Poor Health Habits: Some poor lifestyle habits or lifestyle changes may lead to hair thinning. Actually, whenever a person starts to lead his or her life against biological or natural conditions or starts to habit something that is not usual, immunity of that person downfall slowly. Here are some poor health habits that often ruin a person’s health and then causes hair fall and thinning at an abnormal rate-
    • Poor eating habit with overindulgence on fast foods.
    • Smoking and alcoholism
    • Too much stress and tension
    • Habit of staying awake late at night.
  • Hair Thinning Caused Due to Medication Use: Medications are meant to cure varieties of diseases. However, in certain situations, medications may initiate hair thinning and hair falls. This is known as drug induced hair fall. Drugs cause hair thinning and hair loss by disturbing the normal cycle of hair growth on the scalp. Medication can initiate two types of hair losses – Anagen effluvium and Telogen effluvium. The anagen phase is a period when hair grows on the scalp and telogen phase is a period when hair stays on the scalp. After the end of telogen phase, hair falls off automatically. Some common types of drugs that may cause hair loss are as follows–
    • Antibiotics
    • Antidepressants
    • Birth Control pills
    • Anticlotting Drugs
    • Epilepsy Drugs
    • High BP controlling drugs
    • Steroids
    • Thyroid medications
    • Weight loss drugs.

These drugs cause Telogen effluvium. On the other hand, drugs used for chemotherapy like Adriamycin, Doxorubicin, Docetaxel, Etoposide etc. cause Anagen effluvium.

What Causes Hair Thinning in Children?

Though hair loss in children in not a common problem, children who suffer from this problem are mostly diagnosed with any one or more of the below mentioned issues –
Hair Thinning in Children Caused Due to Tinea Capitis: This is commonly known as ringworm of the scalp, which is a disease triggered by a fungal infection of the skin of the scalp. If not treated in time, it can spread on the eyebrows, and eyelashes. In advanced stages it can even attack hair shafts and follicles.

  • Alopecia Areata Can Cause Hair Thinning in Children: It is a sudden appearance of small patches of hair loss. The patches look smooth without any inflammation, scaling or broken hair. These patches may spread all over the scalp and appears overnight in most of the cases.
  • Trauma as a Cause of Hair Thinning in Children: Trauma is another cause of hair loss in children when the hair shaft gets severely damaged due to traction or friction. The common cause of traction is consistent pressure caused by tight braids and pony tails etc., while friction may occur due to regular rubbing against a bed or back of a chair.
  • Nutritional Deficiency in Children Can Cause Hair Thinning: Though not common, certain nutritional deficiencies like lack of Vitamin H, Vitamin B and minerals may cause hair thinning and hair loss in children.

Hair fall is inevitable particularly when there is a family history of the same. Again, some diseases, medicines or unhealthy lifestyles may also trigger hair fall.

Moreover, one should be cautious about his or her lifestyle and eating habit. Over indulgence on fast foods, alcohol, and smoking etc. may aggravate the condition even further. Otherwise, hair fall is a normal event and it affects over 85% of people worldwide by the age of 50.
