What causes hair fall?

There are many different causes of hair fall, including:

1. Genetics: Some people are more likely to experience hair loss due to their genes.

2. Hormonal changes: Hair loss can be caused by changes in hormone levels, such as those that occur during pregnancy, menopause, or with certain medical conditions like Polycystic ovary syndrome (PCOS) or thyroid problems.

3. Medical conditions: Certain medical conditions, such as alopecia areata, lupus, diabetes, and cancer, can cause hair loss.

4. Medications: Some medications, such as chemotherapy drugs, antidepressants, and anticoagulants, can cause hair loss as a side effect.

5. Stress: Severe stress can cause temporary hair loss.

6. Aging: As people age, their hair follicles gradually shrink and produce thinner, weaker hair. This can lead to age-related hair loss.

7. Trauma: Physical trauma to the scalp, such as a burn or injury, can cause hair loss.

8. Nutritional deficiencies: Deficiencies in certain nutrients, such as iron, zinc, vitamin D, and B vitamins, can contribute to hair loss.

9. Chemical hair treatments: Using harsh chemicals like hair dyes, bleaches, and relaxers can damage hair and lead to hair loss.

10. Excessive hairstyling: Tight hairstyles, such as braids or cornrows, can put tension on the hair follicles and cause traction alopecia.
