Avoid using your blow dryer or any other heat generating styling device daily. By giving your hair a break from the heat, you are reducing the potential damage that these styling appliances can do to your hair. Dryness, split-ends and breakage are signs to look for. Remember, the hotter the device, the more damage it can cause, so try a lower setting or air dry your hair whenever possible. Also, overexposure of your scalp to high temperatures can cause dryness and flaking. So, if dandruff is already a concern for you, the use of a hot blow dryer can actually further irritate your scalp and cause more flakes to loosen. To help restore hydration to your hair, as well as minimize the flaking, look for conditioners that contain a medicated antidandruff ingredient, such as pyrithione zinc. This key ingredient reduces shedding by slowing skin cell turnover and eliminating the fungus that causes dandruff. Unlike traditional conditioners, antidandruff formulations must be applied to both the scalp and hair shaft in order to derive the combined benefits of moisturization and control of flaking.
