Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men.
An increase in hair loss may result from a health-related issue, such as alopecia, a nutrient deficiency, pregnancy, or medication use. Treatment will depend on the cause, but avoiding heat treatment and other lifestyle tips may help manage it.
Various chronic or inflammatory disorders, autoimmune diseases or chronic infections may also cause diffuse telogen hair loss. Nutritional deficiencies, especially of iron or zinc, protein, fatty acids or vitamin D, are other possible causes, as well as extreme caloric restriction and crash diets.
It's normal to shed between 50 and 100 hairs a day. When the body sheds significantly more hairs every day, a person has excessive hair shedding. The medical term for this condition is telogen effluvium.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss. Vitamin B2 (riboflavin) is a component of two important coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) [22].
Severe and prolonged hypothyroidism and hyperthyroidism can cause loss of hair. The loss is diffuse and involves the entire scalp rather than discrete areas. The hair appears uniformly sparse. Regrowth is usual with successful treatment of the thyroid disorder, though it will take several months and may be incomplete.
While men usually see a receding hairline, women tend to lose hair from the top of their scalp. The gap on the part of your hair may widen, or you may notice bald spots when you put your hair up.
The most common form of diffuse hair loss is telogen effluvium, which results in loss of more than 200 scalp hairs per day. It typically develops after an acute event, such as a severe illness, major surgery, thyroid disease, pregnancy, iron-deficiency anemia, malnutrition or rapid weight loss, or vitamin D deficiency.
As with male pattern baldness, female pattern baldness comes from hormone imbalances, specifically dihydrotestosterone imbalances, or DHT. This hormone is similar in structure to testosterone, but it is significantly more potent [3]. DHT can attach to receptors on the hair follicles, causing the follicles to shrink.
Symptom of a medical illness — Hair loss can be one of the symptoms of a medical illness, such as systemic lupus erythematosus (lupus), syphilis, a thyroid disorder (such as hypothyroidism or hyperthyroidism), a sex-hormone imbalance or a serious nutritional problem, especially a deficiency of protein, iron, zinc or ...
Iron and Hair Health. If you are not getting enough iron through your diet, you may experience excessive hair shedding (Telogen Effluvium). You may also find that your hair will not grow past a certain length.
If your doctor suspects that an underlying medical condition may be the cause of hair loss, a blood test or scalp biopsy may be recommended. All of these diagnostic tests can be conducted in your dermatologist's office.
Magnesium deficiency can lead to conditions such as premature graying and hair loss, along with various other issues such as bone density problems, gastro problems, and nerve and muscle function issues.
Although research is somewhat limited, there's evidence that vitamin D deficiency can affect healthy hair growth, potentially resulting in shedding, thinning and patchy hair loss that affects certain parts of your scalp.
A visible scalp through your hair can be a sign that it's thinning (but not always). The factors that contribute to thinning hair (and thus a visible scalp) include stress, diet, vitamin deficiency and ageing.
Alopecia Areata: An autoimmune disease that affects the skin and scalp, causing hair to suddenly fall out. Thyroid Problems: An overactive or underactive thyroid can both be contributing factors to hair loss. Cancer: Cancer such as Hodgkin's lymphoma may cause hair loss but typically, chemotherapy is the primary cause.
Under normal circumstances, it is possible to lose anywhere between 120-160 strands of hair a day. If you experience excessive hair loss it can be an indication of an abnormality within the scalp, symptoms of which may include itchiness, redness, flakes, and pus.
One example where a link has been found is with Hodgkin's Lymphoma. In rare cases where the disease spreads to the skin, it has been known to cause hair loss. It's an extreme version of the irritation that the disease can cause to issues, which most frequently reflects as more mild symptoms, like itching.
Long-term, or chronic, stress puts people at risk for a variety of health problems. These can include depression and anxiety, as well as problems with digestion and sleep. Chronic stress has also long been linked to hair loss, but the reasons weren't well understood.
Low levels of estrogen and progesterone means your hair may start to fall out sooner and grow more slowly. The goal of hormone replacement treatment during menopause is to help your body attain healthy, balanced hormone levels, which is why many women may notice changes in hair thinning once they start treatment.
