It's really difficult to straighten fine hair without damaging it, but there are tools that can help minimize damage, you just need to know which features to look for. The best flat irons for fine hair should have low heat settings and ultra-smooth plates with even heat distribution.
While people with thick hair need temperatures around 400-degrees Fahrenheit to straighten their hair, this level of heat can fry fine hair so it's vital you use a hot tool with temperature control. Ideally, you should look for a hair straightener that can be set to lower than 200-degrees Fahrenheit — this way, you'll be using the least amount of heat possible to straighten and style.
You're also going to want smooth plates with well-dispersed heat, so you only have to pass over each section of hair once. More passes means more heat exposure, so poorly heated plates can cause damage even at low temperatures. Ceramic or ceramic-coated plates have an excellent reputation for evenly distributing heat, as well as leaving hair silky smooth. But today's market is packed with high-tech features, too, like tourmaline and infrared heat that promise to reduce damage and leave hair looking and feeling healthier.
Not sure where to start? I've put together this list of some of the best flat irons for fine hair including budget-friendly options alongside investment-worthy purchases.
