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 personal 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. If dandruff is a concern, the use of a hot blow dryer can actually dry and irritate your scalp and cause more flakes to loosen. To help restore hydration to your hair as well as minimize the flaking, look for a conditioner that contains a medicated antidandruff ingredient, such as pyrithione zinc, which is a key ingredient that reduces shedding by reducing skin cell turnover. Unllike traditional conditioners, antidandruff formulations must be applied to both the scalp and hair shaft to derive the combined benefits of moisturization and control of flaking.
