Common causes of hair thinning
Hair thinning can result from a range of factors. Typical causes include genetic predisposition (androgenetic hair loss), hormonal changes (thyroid disorders, postpartum shifts), stress-related telogen effluvium, nutritional deficiencies such as low iron or protein, scalp infections and inflammatory conditions, traction from tight hairstyles, and structural changes with aging. Systemic illnesses and lifestyle factors may also affect hair density.
