The most common cause of hair loss is hereditary pattern baldness, also known as androgenetic alopecia. This condition is influenced by genetic factors and can affect both men and women. Hair gradually thins and falls out in predictable patterns.
Hormonal imbalances, such as excessive production of dihydrotestosterone (DHT) in conditions like polycystic ovary syndrome (PCOS), can also contribute to hair thinning.
Various medical conditions, including autoimmune diseases like alopecia areata and scalp infections, can cause hair loss. Medical treatments like chemotherapy & radiation therapy can lead to temporary hair loss as well.
Some medications, including those used for cancer, arthritis, depression, heart problems, gout, and high blood pressure, can lead to hair loss as a side effect.
Inadequate intake of essential nutrients, such as iron, zinc, biotin, and protein, can affect the health of hair follicles and contribute to hair loss.
Significant physical or emotional stress, such as a major surgery, traumatic event, or extreme weight loss, can disrupt the hair growth cycle and lead to temporary hair shedding.
Excessive pulling or tension on the hair, often due to tight hairstyles like braids, ponytails, and cornrows, can cause a type of hair loss called traction alopecia.
