Flat irons are a convenient, effective way to straighten and tame curly locks at home. However, you might want to go with a lower-heat alternative that can pose less risk of damage to your hair like split ends and frizz. This is where hair straightener brushes come in.
The newly added GHD Glide Professional comes from a British company whose initials stand for “good hair day,” and it will give you smooth, straight hair without causing unnecessary exposure to high heat levels. Although it proves a bit of an investment, it can give salon-quality results. (It’s sold in more than 50,000 salons worldwide.) What makes it so convenient is that you only need to run it through your hair minimally for your desired style. This is thanks to its combination of powerful ceramic technology and an ionizer.
The Drybar The Brush Crush straightens and adds shine without any unhealthy side effects from its heat, since seals the cuticle in the process. It offers digital temperature control and is designed with safety in mind, thanks to its automatic shutoff feature that kicks in after it’s been on for 60 minutes. You can purchase it with confidence, thanks to its generous 2-year warranty.
The InStyler Straight Up is another pick that offers safety-minded features, as its cool-touch bristles prevent its heat from getting too close to your scalp. It heats up and is ready to use in just 30 seconds and features a professional-quality swivel cord that keeps it from becoming tangled as you work your magic in front of the mirror.
The budget-friendly Revlon XL is great for the occasional hair straightener or anyone who doesn’t want to invest much money in this type of styling tool. However, it’s also a reliable choice with duo-detangling bristles for snag-free styling, as well as 10 heat settings that reach up to 430 degrees Fahrenheit. It’s built with a lightweight, ergonomic design and offers dual voltage for use anywhere in the world.
When using these tools, professionals recommend you spritz your hair with a heat protector to prevent damage. This will help to lock in moisture to keep your tresses healthy and free of frizz.
How Hair Straightening Brushes Revolutionized Styling
Straightening brushes have heat-safe rubber tips at the end of the comb teeth and leave almost no part of the heating element entirely exposed.
When a person used to want to straighten their hair, they would need two tools; both a flat iron and a hair brush. While this is still a viable option, the straightening hair brush consolidates two tools into one, ironing the hair while also removing tangles. There are two main types of straightening brushes. The first is called the hot brush. This variety is safe to use on wet hair because it sends out a lower heat, and has a rotating mechanism so heat is never applied for too long on any one chunk of hair. Using lower heat on wet hair is important because strands are at their weakest when damp. Newer models can straighten hair that has been dried, and apply constant heat.
Straightening brushes distance the hair slightly from the heating component, as opposed to flat irons, which press hair strands firmly against it. For this reason, straightening brushes can be more gentle on damaged hair. Another unique element of the straightening brush is that it emits heat and frizz-decreasing ions in the same moment it runs comb teeth through the hair. This actually makes tangled hair easier to brush through because the strands will not stick together as much, and the bonds are partially broken.
Most women who have used flat irons have burnt themselves, at least mildly. Straightening brushes have heat-safe rubber tips at the end of the comb teeth and leave almost no part of the heating element entirely exposed. This makes them much safer and reduces the incidents of burns.
Traits Of A Quality Straightening Brush
One study evaluated the beauty habits of 2,000 women and found that the average woman spends ten days of her life doing her hair. A straightening brush can, hopefully, reduce that number. For the fastest results, look for a straightening brush that can be set to high temperatures.
Women who suffer from frizzy hair should consider a straightener that delivers negative ions.
Also ensure it has an automatic shut-off feature since you do not want to accidentally leave a hot appliance on in your home, posing the risk of burns or even causing a fire. Contact burns from straightening appliances can be severe enough to send someone to the hospital. A straightening brush that heats up fast also reduces the chances one leaves it on and unattended.
If you do not have someone to help you straighten the back of your hair, you will have to reach around and over your head. A straightening brush with a rotating wire will make this easy to do, without running the risk of pulling the cord out of the wall. Dropping a straightening brush while it is turned on can also be quite dangerous, which is why you should look for one with a rubber, non-slip grip. Many models even offer short circuit protection.
Women who suffer from frizzy hair should consider a straightener that delivers negative ions. These help to produce extra silky strands. If you would like to integrate a straightening brush into your at-home spa day, look for one that has a massage setting in the head. Many also feature an LCD screen that displays the temperature in both Celsius and Fahrenheit.
The Science Behind Changing Hair Shape
To understand how hair becomes straight, curly, or altered in any way one must understand the composition of hair. Hair is composed of a protein called keratin. Keratin is made of sulfur-containing amino acids and the atoms in these create disulphide bonds. These bonds are what make hair strong; it is very difficult to break a strand of hair without scissors.
But now they form and hold keratin molecules in place in a different shape.
Even tearing a strand in half with one's hands takes a great amount of force, relative to the tiny diameter of the hair. Disulphide bonds keep hair from falling off of one's head while they walk through the wind and put their hair through all sorts of stress. The bonds are also what keep hair curly, wavy or straight because they make keratin molecules stay in place.
Appliances that seek to alter the shape of one's hair, like curling irons, straightening brushes and flat irons work by breaking disulphide bonds through the use of heat. When disulphide bonds break, the molecules of the keratin can move slightly. This movement appears to the human eye as a new shape of the hair, whether that be straight, curly or something else.
Disulphide bonds cannot remain broken forever. Once the hair cools down, the bonds reform. But now they form and hold keratin molecules in place in a different shape. Water can once again break these bonds, which is why a rainy day can ruin a perm, or make straightened hair curly again.
