Severe dandruff with itching can sometimes lead to temporary hair fall because constant scalp irritation and scratching may weaken the hair roots. Dandruff is commonly caused by excess scalp oil, fungal overgrowth, stress, sweating, irregular hair washing, or sensitivity of the scalp skin. In many cases, controlling dandruff also helps reduce hair fall gradually. Medicated anti-dandruff shampoos containing ketoconazole, zinc pyrithione, selenium sulfide, or salicylic acid are commonly recommended and are usually used 2-3 times a week as advised by a doctor. Leave the shampoo on the scalp for a few minutes before washing to allow it to work properly. Avoid excessive oil application, harsh hair products, frequent scratching, and very hot water on the scalp, as these may worsen irritation. Eating a balanced diet rich in protein, iron, vitamins, nuts, fruits, eggs, green vegetables, and adequate water intake may support healthy hair growth. Stress control, proper sleep, and regular scalp hygiene are also important. Hair fall can also occur due to anaemia, thyroid problems, nutritional deficiencies, hormonal imbalance, or scalp infections, so if the hair loss is severe, patchy, or continues despite dandruff treatment, it is important to consult a dermatologist for proper scalp examination and possible blood tests. Avoid self-use of steroid lotions or multiple hair products without medical advice, because they may worsen scalp problems over time.
