Dry hair and scalp, along with dandruff and hair fall, usually happen when the scalp barrier becomes weak, which can be due to fungal overgrowth (like dandruff), frequent use of harsh shampoos, hot water washing, weather changes, stress, or even nutritional deficiencies such as low iron or vitamin levels. When the scalp is dry and flaky, it can also lead to itching and increased hair shedding because the roots become more sensitive and irritated. Using a mild shampoo suited for dry scalp and washing the hair 2-3 times a week can help maintain balance without stripping natural oils. If dandruff is present, an antifungal shampoo used regularly in the correct way (leaving it on the scalp for a few minutes before rinsing) can reduce flakes and itching. Light oiling may help with dryness, but it should be washed off properly so it does not worsen dandruff. Keeping the scalp clean, avoiding scratching, and reducing heat styling or chemical treatments can also improve hair strength over time. If hair fall is persistent or increasing, or if dandruff keeps returning despite treatment, a dermatologist evaluation is important to check for underlying causes like fungal infection or nutritional deficiencies.
