Hair loss can be caused by various factors, including:
- Genetics: Hereditary hair loss (androgenetic alopecia) is the most common cause, affecting both men and women.
- Hormonal changes: Pregnancy, childbirth, menopause, and thyroid problems can cause temporary or permanent hair loss.
- Medical conditions: Alopecia areata (an autoimmune disorder), scalp infections, and other skin disorders can lead to hair loss.
- Medications: Certain drugs used for cancer, arthritis, depression, heart problems, and high blood pressure may cause hair loss as a side effect.
- Stress: Physical or emotional stress can trigger temporary hair loss.
- Nutritional deficiencies: Lack of iron, protein, or other nutrients can affect hair growth.
- Hairstyles and treatments: Tight hairstyles or harsh chemical treatments can damage hair follicles.
- Aging: Hair naturally thins with age due to slower growth and hormonal changes.
- Scalp conditions: Psoriasis and other scalp issues can interfere with hair growth.
- Environmental factors: Exposure to pollutants, radiation, or certain chemicals can cause hair loss.
- Autoimmune diseases: Conditions like lupus can attack hair follicles.
- Rapid weight loss: Sudden changes in diet can lead to temporary hair shedding.
Treatment options vary depending on the cause and may include medications, lifestyle changes, or hair restoration procedures. It’s important to consult a healthcare provider to determine the underlying cause and appropriate treatment for hair loss.
