Severe body and hair odour despite good hygiene may be due to bacterial or fungal overgrowth, excessive sweating, or scalp infection. Hormonal imbalance, diet, or certain medical conditions can also contribute. Keep the skin and scalp clean and dry, and avoid tight or synthetic clothing. Consult a doctor for proper advice and suitable treatment.

Foul-smelling underarm sweat is usually caused by bacteria breaking down sweat on the skin. Poor hygiene, excessive sweating, diet, or hormonal changes can contribute to this problem. Keep the area clean and dry, wear loose cotton clothing, and maintain good personal hygiene. Consult a doctor if the problem persists or is severe.
