Since you have no family history, your hair loss may be triggered by temporary factors like stress, nutritional deficiencies, or hormonal imbalances. For medical regrowth, topical Minoxidil (5%) is the gold standard and highly effective. Additionally, daily supplements containing Biotin, Iron, and Zinc can support recovery if deficiencies exist. Regarding hair oils, Rosemary oil massaged into the scalp has shown scientific promise for hair density, while pumpkin seed oil can support scalp health. However, since the cause isn?t genetic, I highly recommend consulting a dermatologist to run blood tests (checking thyroid and vitamin levels) to address the root cause.
