If your hormonal tests are normal and you are already taking Eltroxin, ongoing hair fall is often due to non-hormonal factors such as stress, nutritional deficiencies (iron, protein, vitamin B12, vitamin D), dandruff-related scalp inflammation, or genetic tendency like early Androgenetic alopecia. Managing it involves treating the scalp first with anti-dandruff shampoos (like those containing ketoconazole or zinc), ensuring a balanced diet rich in protein, leafy vegetables, nuts, and fruits, and correcting any deficiencies with your doctor's guidance. Gentle hair care (avoiding tight hairstyles, heat, and harsh chemicals) and regular oiling can help reduce breakage, while treatments like Minoxidil may be advised to promote regrowth if needed. Premature greying is often genetic or linked to deficiencies and is harder to reverse, but improving nutrition and overall health may slow its progression. If hair fall is severe or persistent, consult a dermatologist for proper evaluation and targeted treatment.
