Hair loss is a natural phenomenon considered normal given that hair regenerates, but it can be a cosmetic problem when lost hairs are bot replaced by new ones. Starting with chronic stress and an unbalanced diet, there are numerous causes, some surprising, for hair loss.
Loss of about 100 hairs in 24 hours is normal, but the appearance of hair thinning and increased visibility of the scalp announces a problem in the natural process of growth and regeneration. When your hair is thinning amid disorders as pattern baldness, hair loss can be permanent.
Here are some hidden causes of hair loss:
1. Physiological trauma
When the body is subjected to chronic stress, the natural cycle of hair growth can be disrupted. In this case, the hair thins and more extensive portions of the scalp can be seen with the naked eye.
Physiological trauma, therefore, are startling causes of hair loss, translating to strong shock (severe injury, major surgery, chronic illness, etc.). The affected follicles cease to produce new hairs, setting up a loss of about 75 % of the hair (even after months of experimentation of trauma).
2. Hormonal disorders
Another surprising cause of hair loss are hormonal disorders, especially those suffered during pregnancy and after birth. It takes a long time after pregnancy for hormonal balance to be restored, so it frequently happens that new mothers notice a loss of hair volume or appearance of visible areas of the scalp, usually after three months of birth.
Fortunately, hormone rebalancing reactivates follicles, so hair regrowth always happens naturally.
3. Thyroid diseases
Both hypothyroidism (slow functioning of the thyroid gland) and hyperthyroidism (overactive thyroid) can trigger hair loss visible, having also a hormonal background. Hormones regulate nearly all body functions, so treatment of thyroid diseases resolves hormonal disorders that cause hair problems.
4. Side effects of drugs
Even drugs administered for common health problems can influence the natural cycle of hair regeneration. Blood thinning drug, oral contraceptives, antidepressants or beta blockers have hair loss as a side effect.
Also, pills with high concentrations of vitamin A affect the hair. Drugs used in chemotherapy cause temporary hair loss, sometimes completely, followed by complete regeneration after cessation of treatment.
5. Emotional stress
Traumatic events produce a level of life -threatening emotional stress, another cause of hair loss. Once installed state of peace and psychological balance, regeneration of capillaries goes back to normal. In the same conditions of emotional stress, the body’s white blood cells can attack the hair follicles, causing loss of hairs in some areas of the scalp.
6. Nutritional deficiencies
Hair health is directly influenced by nutrients coming from food, such as vitamins and proteins. An unbalanced diet can cause hair loss, thinning hairline and even installing of alopecia.
7. Excessive hairdressing
People who frequently style their hair, using cosmetics with more chemicals in their composition and thermal tools (curling iron), endanger the health of the hair. Even some very tight hairstyles that keep your hair very tight weaken the roots.
Infections affect the natural form of the hair and they can cause loss to a significant degree. An infection that is manifested by high fever or a fungal infection of skin tissue or bacterial infections (such as syphilis) may be responsible for the installation of alopecia.
In this case, the result of a special treatment is the only way for the regeneration of the hair.
Alopecia areata (a form of hair loss where the hair follicles remain intact and visible on inspection) is often associated with symptoms of autoimmune diseases, such as diabetes or lupus. Unfortunately, this type of loss is not always reversible and sometimes it can be permanent. The solution in this case is surgery.
10. Skin cancer
Skin cancer is another cause of hair loss, either because of the pathogen changes occurring in skin cells or because of undergoing chemotherapy treatments.
Among the many clinical manifestations of liver cirrhosis (loss of appetite, nausea, fatigue, sensitive skin, palmar erythema, itching, dark urine), uncontrolled hair loss is included.
12. Vegetarian lifestyle
Vegetarians may experience hair loss because of insufficient iron intake (derived mainly from meat).
13. Polycystic Ovarian Syndrome
Polycystic ovary syndrome can cause massive loss of hair so either growth in unwanted areas of the body.
14. Seborrheic dermatitis
A condition specific to the period of adolescence, seborrheic dermatitis can be a cause of hair loss, and after following a dermatological treatment, regeneration is complete.
15. Eating disorders
People who suffer from bulimia or anorexia get to lose a good portion of their hair because of unbalanced nutrition and emotional stress.
