What to Look For
When buying a hair dryer, professionals recommend you base your purchase on a few things: shine, often in the form of an ion generator; cost; length of time the dryer takes; and a heat shield to prevent you from getting burned. For fine hair, look for a dryer that has built-in fans to give volume, and heating coils to retain moisture in the hair.
Avoid heavy or bulky hair dryers, which are inconvenient and unnecessary. Make sure the dryer has fans in it to avoid over-heating. Make sure the dryer has protection measures and won't burn your hair.
Where to Buy
The best place to buy a hairdryer is in a professional hair salon. There, you can ask an employee which dryer they prefer and why, and get an opinion from someone who uses the product often. Otherwise, you can browse hairdryers online at sites such as Amazon.com and Sephora.com, which will let you browse reviews, as well.
The cost of hairdryers can vary widely. Most well-reviewed high-end brands will run you anywhere from $60 to $350. Women's Health Mag recommends the Conair Infiniti Nano Silver Hair Styler at $62 for best budget and quality, and the Chi Nano Dual Air Flow Ceramic at $256 for fine hair.
