Buying Guide: Things to Consider When Looking for a Hair Straightener for Damaged Hair

So, you want a flat iron for your damaged hair, but you’re not sure how to get started? No problem. If you’re looking for the perfect straightener, here are a few things to consider:

  • Plate material: The most common materials are ceramic, titanium, and tourmaline. Ceramic and tourmaline produce similar results and are best for fine hair. Titanium is good for thick or curly hair and is lighter in weight than the other two.

    With damaged, dry hair, a ceramic iron is the best option, it produces gentle heat and distributes the heat evenly across the hair, but make sure it is made entirely out of ceramic and not just ceramic-coated.
  • Plate size: The plates on hair straighteners range from around .75 inches to 1.75 inches or larger. As a general rule, small plates are best for short or fine hair, while the bigger plates are better for people with long hair or people who are in a hurry.
  • Negative ions: Choosing a plat iron that emits negative ions will help you reduce frizz and increase shine. It will also help lock in moisture and make your hair smoother and healthier.
  • Automatic shut-off feature: Regardless of how good you are at remembering to turn off your curling/straightening iron, this is a great feature to have. It simply provides you with the peace of mind you deserve.
  • Cord length: Longer cords are better (duh!), and the ones that provide a 360-degree swivel feature are even better because they are much easier to work with.

Tips to Straighten Damaged Hair

The best way to straighten damaged hair is to treat your hair right before you begin to straighten it. This means shampooing and conditioning with products made for your hair type, and most importantly, making sure you do a deep-conditioning one to three times per week.

You should also never use a straightener unless you put some type of protective treatment in the hair beforehand. Most of these products are available in a cream or a spray, and you simply apply it before you start to straighten your hair.

While you’re straightening your hair, never let the iron go above 340 degrees Fahrenheit. Straighten the hair one to two inches at a time, and use slow movements so it doesn’t damage your hair. To prevent frizz, use products that are silicone-free. Once you’re done, you can use a conditioning serum in your hair for extra protection, but don’t use water-based products because they can reverse the straightening effects.

FAQ - Best Flat Irons for Damaged Hair

Q: Is ceramic or titanium better for damaged hair?

A: If your hair is damaged or it’s prone to be that way, a ceramic straightening iron usually works best because it doesn’t heat fast and also because it distributes heat throughout the hair evenly, thus preventing any one section of hair from getting too hot.

Q: Is it okay to straighten damaged hair?

A: Yes, it is, provided you condition it thoroughly and get it as healthy as possible before you straighten it. Also, make sure you use a protective product on your hair beforehand and a conditioning serum afterward.

Q: Will straightening my hair every day damage it?

A: If your hair is healthy, daily straightening should be fine. But the more damaged it is, the less you should use your straightener. Damaged hair shouldn’t be straightened more than every two to three days. Keep an eye on the condition of your hair to determine how often to use your straightening iron. If your hair is damaged, start with every two to three days, then once it improves, you can go every other day. Only straighten your hair daily if it’s in great condition.

Conclusion: Best Flat Irons for Damaged Hair

Choosing a top-notch hair straightener isn’t as difficult as you think. If you have extremely damaged hair, you may want to wait until its condition has improved before using a flat iron. Once your hair is in better shape, the main thing you want to do is find a high-quality flat iron that won’t dry your hair out or damage your hair even further. Choosing a ceramic iron for thin or short hair and a titanium iron for extra-thick or curly hair is a great start, and you should never slack on keeping your hair well-conditioned and cared for properly.

Indeed, hair that is in good shape can simply take more abuse than hair that is damaged or dry, so regularly conditioning your hair is crucial regardless of your hair type. If you’re going to straighten your hair regularly, you should also cut down on the amount of time you spend blow-drying or dyeing your hair because these things just add to the potential for damage.
