Can I control hereditary hair loss?

Hair loss is mostly caused by geneticsβ€”about 80% of cases are linked to family history, especially on your dad’s side. While you can’t change your genes, you can slow it down by eating a balanced diet, managing stress, and keeping your scalp clean to support hair growth and reduce thinning.
