Blow drying too much may make your scalp dry, which is one of the major causes of dandruff. So, the answer to this question is yes – using your hair dryer excessively and aggressively can lead to dandruff on your scalp and shoulders. To prevent this, make sure you have got a high-quality dryer with appropriate power that is compatible with your hair type. Prevent your scalp from overheating by switching to cooling mode so that it balances the heat inside out. If you handle it well by following the instructions carefully, nothing can go wrong.
