I’ve never curled my hair because I’ve never figured it out. And then I saw this product. I promise it will be easy. You don’t have to do much. It is so simple that even I can use it easily. Make good use of my money!!

How To Curl Using LANDOT Professional Negative Ion Hair Straightener

  1. Sectioning hair: Take the section of hair and comb through it by using a brush. You have to make the hair as tight as possible, loose hair generally doesn’t curl, because the hair straightener will start to straighten them out instead of curling. So be sure to make them as tight as you can.
  2. Applying heat onto the hair: Take your flat iron and start from the top of the hair, close to your scalp. Move slowly down the hair while applying about a max of 10 seconds of heat onto one spot of the section. It will take a bit longer for the heat to reach the center of the inside, which is why it’s good to go slower rather than faster. Fast movements will result in the outside layer of the hair is curled, but the inside being sloppy and flat.
  3. Brushing curly hair: Don’t use a comb for this, use your fingers to brush through the curls. With a comb or brush, you would be undoing all the work you just put into doing your hair, the combing would take the curls right out.

Negative Ion Hair Straightener Buying Guide

What Is A Negative Ion Hair Straightener?

An ionic hair straightener is an electrical appliance designed to straighten and smooth hair while also improving its strength and overall health.

The ion titanium flat iron features a built-in Ionic Generator which can emit millions of negative ions to eliminate static electricity, lock more moisture to create smooth,shiny-looking hair, and reduce frizz.

Negative ions close the cuticle layer to create a smooth, silky hair surface and seal in the hair’s natural moisture. This provides ultimate shine, color, and moisture protection for hair. Negative ions also eliminate static electricity on the hair surface so hair is left silky and frizz-free.

How Does A Negative Ion Hair Straightener Work?

Straighteners generally use heat to press and smooth hair, but the introduction of charged ions is intended to make this process both longer-lasting and less damaging.

Ionic hair care is a relatively new trend, but ions are a part of chemistry that’s involved in almost everything. Ions are essentially atoms or molecules that have lost or gained an electron. In general, most atoms and molecules start out with an equal number of these charged particulates, which generate energy. Losing or gaining electrons impacts the behavior of the cell itself.

Most experts agree that ions and their charges are an important part of hair health, and they may also be able to impact some aspects of human health and mood, too. Most hair stands are positively charged as a matter of course, and ionic hair straighteners usually emit negative ions as a consequence.

When the negative particulates interact or come in contact with the positive ones of the hair follicle, they neutralize; in theory, this causes a restoration in electron balance that can improve each hair on a chemical level.

Features To Look For In A Negative Ion Hair Straightener

Ionic Technology

If a hair straightening tool has this feature, it is able to generate negative ions. Our hair, on the other hand, is charged with positive ions. In the process of ironing, positive ions in the hair are neutralized by negative ions resulting in the following advantages:

  • A decrease in the static charge of the hair helps to eliminate frizz.
  • Supple and sleek hair.
  • Hair attains its natural moisture.
  • The hair looks glossy and healthy.

Therefore, the ionic feature is very effective, which is very favorable if you have unruly hair or if it is fine and thin.

Hair Type

The more difficult it is to manage your hair, the wider the plates of the hair straightener would you need. This means if you have tight curls that are difficult to manage, you need an ion hair straightener with wider plates while narrow plates can be used for short, wavy hair that’s comparatively easier to manage.

Heat Settings

It is always best to choose a wireless flat iron that has multiple heat setting options. This is very useful as you can operate the straightener according to your hair’s requirements and even change the heat setting as per your convenience. Another thing that is helpful is a display light that shows you the temperature that you have selected.

Plate Size

There are several ion straightener options available in various sizes- narrow, wide, etc. If you only straighten out your fringe or have fine short hair, a small one will work just fine. But if you do have thick, coarse hair that’s difficult to straighten, you’ll need a straightener with wider plates.

Weight & Ease Of Use

This one is a no-brainer. It is obvious that the best ion hair straightener is perfect for traveling or simply carrying around in your purse if you are someone who requires frequent touch-ups. So, a lightweight cordless hair straightener is what you must look for.

Ion straighteners come in a variety of weights. Some hair straighteners may be too heavy to use comfortably for long, so if you’ve coarse, long, or very curly hair opt for a lightweight model so that it doesn’t stress your hand, as straightening thick hair is a time-consuming process and doing so with a bulky straightener is no less dilemma.

Also, look for a long, swivel power cord as this makes styling your hair easier, this causes no stress on your wrist, and also you can work at your desired angle.

Plate Material

  • Ceramic: It evenly distributes heat throughout the plates and is considered to be safe as it cannot burn hair easily.
  • Titanium: These plates heat up faster, so they can prolong the battery life of your cordless straightener. But if they are on your hair for too long, they are likely to cause heat damage.
  • Tourmaline: Tourmaline is a crystalline mineral that is crushed up and coated over flat iron plates. This substance is said to make your hair shinier and reduce frizz significantly.

Common Questions About Negative Ion Hair Straightener

Are negative ion straighteners good?

5.0 out of 5 starsGreat product, great price! This iron does take some getting used to but is really great once you get the form down. Work great for my long medium thick hair.

What does ion mean on straighteners?

An ionic flat iron straightens hair, giving it a smoother, glossier look. Ionic hair care is a relatively new trend, but ions are a part of chemistry that’s involved in almost everything. Ions are essentially atoms or molecules that have lost or gained an electron.

Does ionic straighten damaged hair?

Experts agree that using tools that have ceramic, far-infrared, ionic, or titanium technology leaves hair smooth and manageable in no time at all, and with minimal damage.

A professional ceramic tourmaline ionic flat iron has unbelievably high ratings because of its ceramic plates, ionizing technology, and infrared heat.

What are the benefits of ionic treatments?

An ionic hair straightener is a little bit different in that it is designed also to neutralize the positive ions found on hair. According to most reports, equalizing the cellular composition of hair follicles can give them a smoother, healthier look though it should be noted that whether they actually are healthier is open for some debate.

Results depend at least in part on individual hair characteristics and the overall manufacturing integrity of the device. The results of ionic hair treatments aren’t widely established, and things can vary a lot from person to person and tool to tool.

Is tourmaline the same as ionic?

Ionic hot tools can also go by “nano-ionic” or “tourmaline ionic,” but don’t worry, they all do the same thing: Reduce frizz and flyaways and boost radiance.

Why is infrared important when using flat irons?

Far infrared heat penetrates the hair to heat it gently from within. This creates a different type of heat that doesn’t heat the hair. Instead, more heat is delivered directly to the hair shaft so hair is suppler and can be worked more quickly and easily. Because less heat is delivered to the surface, hair is not damaged.

Enjoy Your New Negative Ion Hair Straightener

Negative ions close the cuticle layer to create a smooth, silky hair surface and seal in the hair’s natural moisture. Remember an ion flat iron straightens hair, giving it a smoother, glossier look. You too can take advantage of these benefits for your mane with the best ion flat iron.
