Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. A dry scalp can cause dandruff, those embarrassing white flakes that appear on your clothing and your hair. A dry scalp can also be itchy, red, and irritated, and make your hair appear dry and dull. Your scalp can dry out for a number of reasons, including: 1. Eczema 2. Dietary deficiencies 3. Cold and dry weather 4. Too-frequent shampooing 5. Hair products that often contain alcohol, which can dry out your hair. Treatment 1. Conditioning or hot oil treatment at your local drug or beauty supply store. If you use a hot oil treatment, make sure it isn t too hot; warm oil or a deep conditioner applied the scalp twice a week can help moisturize and soothe an itchy, dry scalp. 2. Instead, shampoo every other day with warm (not hot) water; frequent washing and hot water can dry out your hair and your scalp. Also avoid gels, mousses, hairsprays, and other products that contain alcohol and can dry out your scalp and hair. Limit the use of heat appliances, like a blow dryer, to give hair a chance to recover. 3. If a dry scalp is producing white flakes, treat yourself to a gentle scalp massage. Stimulate your scalp with your fingertips as you shampoo or when applying a hot oil or deep conditioning treatment to your scalp. 4. Eating the wrong foods can impact your hair and scalp as well. Too many sugary foods can lead to a dry scalp and cause flaking, so limit desserts and trips to the candy jar. Even spicy foods can trigger dandruff, so try to avoid them and see if you notice any improvement. Please consult your dermatologist he will examine and treat you accordingly. Take care.
