1. Hereditary Factors: You will likely have a hair loss problem if your parents do. Alopecia is normally caused due to genetics. While this is more evident in men, women too are likely to develop genetically inherited alopecia.
2. Hormonal Changes: Hormonal changes in the body increase the sensitivity of hair follicles, weaken the hair roots, and cause excess hair fall. Issues like menopause, ovarian cysts, hypothyroidism, and hyperthyroidism change the body’s hormonal balance and may lead to hair loss.
3. Pregnancy: During and after pregnancy, most women experience frequent dehydration, fatigue, and hormonal imbalances. These issues increase sensitivity in the hair follicles and create unfavourable scalp conditions, leading to chronic hair loss.
4. Physical and Mental Stress: Drastic and excessive weight loss, persistent illness, and excessive physical labour may exhaust and dehydrate the body. This can cause the hair follicles to become malnourished and weak, leading to hair loss.
5. Scalp Infections: Fungal, bacterial, and viral infections like seborrheic dermatitis and psoriasis on the scalp can weaken hair roots and damage hair follicles. These infections can eventually lead to hair thinning and breakage.
6. Autoimmune Disorders: Autoimmune disorders like alopecia areata are characterized by hair loss that happens when the immune system attacks the hair follicles. While there are treatments to reduce this type of hair loss, there is no definite cure.
7. Medication and Treatments: Certain medical conditions call for treatments and surgeries that may cure the ailment, but cause hair loss as a side effect. Treatments like chemotherapy, steroids, typhoid medications, heart disease, depression, etc. may cause extreme hair fall.
8. Over-processing and Styling: Going overboard with chemical hair treatments and hot styling tools can lead to hair fall. Heavy usage of hair products and accessories can lead to hair loss. Some hair products, like those containing sulphates, may harm your scalp in the long run. Hairstyles that require the hair to be pulled tight (like tight braids or ponytails) can also cause hair fall.
9. Iron Deficiency, Anemia, and Blood Loss: Deficiency of red blood cells in the body, sudden blood loss, and insufficient iron levels in the body can also cause hair loss.
10. Crash Diets and Malnutrition: Insufficient nutrient intake or being on a crash diet can cause malnourishment, leading to excessive hair fall.
11. Over-Supplementation: Over-supplementation of nutrients like vitamins A and E, and selenium, has been found to cause hair loss as well. Consulting your doctor before going for any supplements is ideal. Also, it is better to get your nutrients first from organic foods and natural sources.
