1. Nutrition and diet: Poor nutrition, rapid weight loss, a high consumption of animal fats and deficiencies in biotin, iron, protein and zinc can reduce vital amino acid and vitamin absorption needed for hair growth.
2. Ageing: Causes all kinds of health problems and it can also be one of causes of hair loss. Hair loss is one of the biggest giveaway of aging. As one gets older, the follicles deteriorate.
3. Stress and trauma: Stress produces increased levels of testosterone, which converts to DHT and interrupts the hair growth cycle. Stress and trauma can also constrict the blood supply to the capillaries, causing a lack of oxygen and nutrient uptake, as well as poor vitamin and nutrient absorption of the hair follicles.
4. Poor hair etiquette: There is good hair etiquette and there is bad hair etiquette. Bad hair etiquette is when you use all the wrong hair styling tools, such as curling irons, strengtheners, gels, sprays, and so on. While all these products might help your hair to look the part, filling you with confidence at the same time, they can also be damaging it, both in the short term and the long term. Some products are more harmful than others, while many people simply cannot get by without using a hair styling tool of some sort, it’s much more helpful to use ones that are going to cause you no harm. Excessive coloring also leads to hair loss.
5. Medication: Everything from birth control to steroids, as well as many blood pressure, diabetic and heart disease and acne medications can cause temporary or permanent hair loss.
6. Life changes: Hormonal changes during pregnancy can lead to temporary hair loss that can last from six months to up to a year after childbirth. Menopausal women can also experience hair loss due to hormonal shifts.
7. Health issues: Thyroid diseases, as well as the side effects of the medications used to treat these diseases, are the most common health-related causes of hair loss.
8. Too Much Vitamin A: Consumption of too much Vitamin A can also be one of causes of hair loss because too much vitamin A can trigger hair loss.
9. Iron deficiency anaemia: Another one of common causes of hair loss is iron deficiency anemia. For women, iron deficiency can occur as a direct result of heavy periods. For both men and women, it can be caused by a diet that is lacking in iron-rich foods. What basically happens is that your blood simply doesn’t have the right amount of red blood cells. And these cells are needed to transfer oxygen to your cells, giving you the right amount of energy to get you through the day. Iron deficiency can cause all kinds of symptoms that is linked to a lack of energy, including weakness, extreme fatigue, headaches, and brain fog. But it can also cause hair loss.
