Keep an eye on the power and heat controls when you get a blow dryer. It is useless to get a powerful unit if you cannot control the heat. The higher setting is most commonly used to clear the moisture. On the other hand, the lower one becomes handy when you want to style the hair. You should rely on it when the hair is about 90% dry. This feature is excellent if your hair is thin and damaged. Not everyone needs to dry hair at impressive power settings. Furthermore, read a few reviews over Oomphed before spending your money as well.
