How do steam flat irons work?

When you press the flat iron against your hair, a steam flat iron will release steam while you straighten your hair. The steam is a warm moister that is designed to keep your hair from getting dry and damaged while straightening. You can also add oils and product into the water container to add protection and more moisture into the steam as its released into your hair.

Most steam flat irons have a comb built into the shaft of the flat iron so that only one hand is needed when doing a pass with the flat iron. The steam is also useful for helping with eliminating any frizz or static in the hair as the negative water ions neutralize any positive static.

Pros and Con’s of Steam Flat Irons-

  • Smoother Shinier Hair- Steam flat irons provided a smoother and shinier finish than other flat irons. The steam helps offer a sleek look when used right.
  • More Efficient- I have found it takes far fewer passes through the hair to get the desired straightness and look you want than a tradition flat iron.
  • Gentler on Your Hair- Steam flat irons when right are far gentler on the hair when used correctly. Steam flat irons are good for damaged or easily damaged hair when used properly. If your hair is prone to dryness or breakage a steam flat iron is probably your best bet to get straight hair without damaging it. Even allure magazine agrees it ranked the number one iron for healthy hair a steam flat iron.
  • Only Really Good For Straightening- Steam flat irons are great for straightening hair but if you want a flat iron that will also crimp, primp, wave, weave, and curl you might want to look at more traditional flat irons. A steam iron will not give you the best of results if you try for a waving hair experience. We would suggest looking at the Babyliss Pro for a broader range of styling technics.
  • Filling up the Water Reservoir- Those who have longer or thicker hair be prepared to refill the water reservoir multiple times before you finished straightening your hair. On most of the flat irons that we have tested the water reservoir only last about 15-20 minutes. For those who have large amounts of hair or thick stubborn hair, this might not be enough time to get entirely done. It sounds petty but stopping and filling up the reservoir is something you don’t have to do with traditional flat irons.
  • You can damage your hair- Any heated hair tool can damage your hair. Just like flat irons, steam irons can damage your hair but in a slightly different way than traditional flat irons. Traditional flat irons can dry out your hair, leaving it more susceptible to heat damage, breakage, or worse catching your hair on fire (think California forest fires during a drought). Steam Irons when misused can hurt you in two ways one the iron is releasing steam that just flat burn you if it comes in contact with your skin. Secondly, if you are not moving fast through your hair, the steam can cause a boiling like interaction with your hair. Adding water to your hair and then keeping the extreme heat on it for an extended time is the same as using boiling water on your hair. Again if you used properly, this should not be an issue we just want to be clear and cover all angles in this guide.
