Eyebrow hair loss can be caused by a number of reasons, but in most cases you do not need to worry too much about it. This is because it is usually a temporary phenomenon associated with nutritional deficiencies and even frequently plucking your eyebrows. What should be pointed out, however, is that sometimes thinning eyebrows is also a symptom and sign for some severe diseases. In this case, you must never treat this issue lightly.
1. Excessive plucking and shaping. Many people try to trim and shape their eyebrows. It is understandable, but sometimes repeatedly plucking eyebrows will damage the hair follicles, which thus makes eyebrow hair regrowth impossible. In this case, please do it only when needed, and make it as close to their natural state as possible.
2. Makeup. Makeup can be one of the possible reasons. Face powder, liquid foundation, mascara, and other cosmetic products can also get you into such trouble.
3. Nutritional deficiencies. Malnutrition can also cause hair loss, including thinning eyebrows. In this case, it makes sense to eat a balanced diet that contains fruits, vegetables and protein. Besides, a daily multivitamin is a great nutrition insurance policy too. If a balanced diet does not help, it is best to see a doctor to have a blood test, which can help identify other potential causes.
4. Eczema or dry skin. Dermatologists can help treat eczema and other skin diseases. Similarly, a doctor can help find out the problem if the daily moisturizer does not work for you.
5. Trichotillomania. People with trichotillomania pull hair from anywhere on the body in private. It gives people strong urges to pull out their eyebrow hair too. Since this is an obsession and compulsion, the patients need psychotherapy rather than medication.
6. Simmonds disease. Also called hypophysial cachexia or pituitary cachexia, this disease is characterized by hair thinning or disappearing, weight loss, listlessness, apathy, drowsiness, poor appetite, and so on. It is caused by the declined function of the anterior lobe of the pituitary gland. This is a diagnosis that carries a poor prognosis. That’s to say, severe coma or even death can occur by any adverse stimuli such as chills, infection, low blood sugar, low salt, drinking too much water, etc.
7. Leprosy. Eyebrow hair loss is one of the early signs of leprosy. This is a chronic infectious skin disease and its main symptoms are damage of the skin and peripheral nerves. And some patients may also suffer from damage to the lymph nodes, eyes, nose, liver, spleen and other organs.
8. Secondary syphilis. Syphilis is a sexually transmitted disease (STD). In this case, hair, including eyebrows and beard, may fall out in patches. Besides of patchy hair loss, other symptoms also include skin rash, headaches, sore throat, and so on. This disease can be treated with antibiotics like Tetracycline, Penicillin G benzathine, and Doxycycline.
9. Hypothyroidism. This disorder means the thyroid fails to excrete enough hormones for your body to regulate metabolism and the use of energy. Hair loss is a common side effect of thyroid disorders and hypothyroidism is no exception. This is the result of reduced metabolic capacity and malnutrition.
10. Autoimmune diseases. Alopecia areata or lupus manifests itself by attacking hair follicles too. It can be disturbing although sometimes it is not life-threatening.
In addition to the above causes, a particular drug may also be the triggers. So it is necessary to first rule out the possibility of recent administration of some certain drugs. If the loss of eyebrows are permanent, eyebrow tattooing is highly recommended since it can be very natural. In extreme cases, some people need to consider eyebrow hair restoration, which now has been recognized as a permanent solution to this problem.
