ghd IV Styler

A New Religion for Hair

"A new religion for hair", that’s how the GHD’s slogan goes. Is it the case though? Let's find out together.

At first glance, the straighter doesn't look any different than hundreds of other irons available out there. However, it might seem so until you take a closer look at it. Under closer inspection, you will notice that the plates of this straightener have a unique design and its heat control is somewhat different.

Naturally, the plates are still the plates, however, due to their rounded edges, you can use this straightener for a whole variety of hairstyles, experimenting with the shape of your curls and waves as you want. With the length of 25 mm, it will be easy to wind your hair around them no matter what you want to do - straighten your strands or make curls.

When it comes to materials, the device doesn't bring anything new to the table and, just like most straighteners produced today, features ceramic plates. This, however, is considered the safest material and can be used on all hair types without the need to worry about damaging your locks.

The heat control is placed between the plates, on the internal part of the handle, instead of being placed on the side of it. This placement is very convenient since there's less chance to inadvertently switch the device off during use. However, it does lack temperature adjustments and operates only at one 185° temperature, which makes it a bad option for those who have brittle/dyed hair.

How good is this religion? It is up to you to decide.

Review of ghd IV Styler

Great For Thick Hair

Still, the ghd IV Styler isn't a bad thing. It is well-built, feels solid in the hand and ensures pretty quick results, so if your hair is coarse and unmanageable, it will definitely get you covered. What's more, it doesn't take ages to heat up, requiring only 30 seconds, which is faster than many other models!

Pivoting towards safety features, the ghd IV Styler isn't void of them. As you would expect, it has a heat-resistant body that doesn't tend to get hot, so you will be able to hold it in your hands comfortably no matter how long the process of straightening/curling will take. The auto power-off feature is also present, turning the device off automatically in 30 minutes of non-use, which can come in handy life-saving in case you do not do that yourself after use. Finally, the device comes with a 2-year warranty from the manufacturer, proving that under careful use it will serve you for a long while.

To summarise this review, if you have normal or thick hair and need a device that will allow you to achieve fantastic results in a few strokes, the ghd IV Style can be a good choice.

Remington Shine Therapy S8500

Plates Infused with Moroccan Oil

If your approach towards hair care is serious, we highly recommend purchasing the Remington S8500 Hair Straightener. This advanced device with ceramic plates will not only help you style your hair beautifully but also nourish it.

The biggest selling point of this hair straightener is its plates. They are infused with Moroccan Argan oil and vitamin E. That’s why every time you style your hair, it will look super-shiny - actually 86% shinier than after using an average flat iron. The floating plates are 25 mm wide and provide even pressure on your hair for the smoothest results possible.

The other thing that users really like about this device is that it has a huge number of temperature settings. There are 9 of them and you can select the desired one with the handy control buttons. Their placement is much more convenient compared to other models: they are situated not between the plates but on the side of the unit. That minimises the chances of you accidentally touching the hot plate and burning yourself. Sill, we strongly advise wearing heat-resistant gloves whenever you use curling or straightening devices.

Above the control buttons, you can see an LCD display that shows the chosen setting. The temperature range of this flat iron is pretty wide (150°C - 230°C), hence this model is suitable for people with both thin and thick hair alike. The heating time is pretty impressive - only 15 seconds. There is also a convenient Turbo mode that makes the device ready for use straight away. This function will be especially handy when you are running late.

Light Design

Moving on, we would like to say that like the majority of modern hairstyling devices, the Remington Hair Straighter is fitted with a safety feature, so it will shut off automatically after 60 minutes of non-use. Hence, there is a low risk of a fire if you forget to turn the iron off while in a rush.

As for the design, this model is made with a nice shiny body. It comes in white with blue plates. The set of this flat iron also includes a heat resistant pouch that comes complete in the same colours. It will become handy if you need to take the straightener with you on a trip.

In the end, we can conclude that the Remington S8500 Hair Straightener is a worthy purchase for those who want to have straight, healthy hair. It doesn’t damage your locks thanks to the advanced plates ifused with vitamin E and Moroccan Argan oil and can make your hair 80% shinier than usual.

BaByliss Pro 235 Elegance

Fashionable Pink

For girls with curly and thick hair looking for a straightener capable of providing great results without the need for raising the temperature to the highest point, we recommend turning towards the BaByliss Pro 235. This model includes an ionization function which allows achieving perfectly straight hair in a few passes, effectively removing frizz and static.

The BaByliss Pro 235 was designed with women's needs in mind. Hence, it has full functionality needed to apply it on different hair types. You can use it on thin, bleached, and coarse hair and worry not that your locks might turn lifeless or lose their gloss. The straightener offers three heat settings that can be adjusted to 180°C, 200°C and 235°C depending on your hair type.

Another proof that this product was designed with women's needs in mind is that it comes in a fashionable pink colour! The manufacturer pretty well knows how girls adore pink. So if your mum or friends have a birthday soon, you can safely buy it as a gift.

For added convenience of use, the iron is fitted with a LED indicator light, telling you when the iron has been heated enough to be used. Generally, it requires just 15 seconds, but this time might be extended a bit if you use it on the max setting.

Review of BaByliss Pro 235 Elegance Straightener

Bright Design

Moving on to the plates, in this model, they are 25% longer than average, which means you'll need less time for straightening. When it comes to the width, they measure 24 mm, which makes them one inch narrower than most. The difference isn't huge but it does make curling easier. However, take note that the plates here are not floating. While many people won't find it a problem, those who are used to the floating design might need more time to get used to it.

A little bonus that contributes to the advantages of the BaByliss Pro 235 is that it comes with a case. You will be able to use it for storage or transportation when travelling. The case is made in a matching colour and from pretty good materials. As we've mentioned travelling, the BaByliss Pro 235 has a multi-voltage feature, meaning you will be able to take it with you on overseas trips too.

As you can see, this straightener isn't just about looks. It is packed with features that will allow you to take care of your hair in a gentle way. So, if you're looking for something as effective as it is stylish, the BaByliss Pro 235 hits the sweet spot.

ghd Platinum+

Smart Straightener

Those who seek a decent hair straightener that can be used for both professional and individual styling may want to take a closer look at the GHD Platinum+ Professional Smart Hair Straightener.

Starting off with the heat levels, this model is quite basic since it heats up to the constant 185°C. However, thanks to the smart construction and innovative technologies, this styler is gentle enough for thin or damaged hair. Also, it can tame thick, unruly hair quite well. 

One of those technologies is Ultra-zone that allows the device to adapt for the particular hair section you're working on. The styler adjusts to your hair type, thickness and personal styling speed. As a result, the straightening becomes more efficient and there is a lower risk of hair damage. On top of that, this technology also helps protect the colour-treated hair and prevents it from getting dull. 

The powerful heating element ensures that the device gets ready for use in just 20 seconds. The unit also automatically shuts off after 30 minutes of no use. 

This model has a universal voltage feature, letting you take it with you when you go travel. But do note that the plug still needs adapter and may be slightly inconvenient to use. It is way too smooth and hard to take out of the socket, especially if your hands are a bit sweaty.

Review of ghd Platinum+ Professional Smart Hair Straightener

Unique Plates to Add Gloss

The plates of this model surely deserve special attention. The precision-milled plates have a special ultra-gloss coating that adds 20% more shine to your locks, makes them smoother and healthier. The plates have an average size of 25 mm.

As for the overall design, this hair straightener has a unique wishbone hinge that ensures there will be no tangling or snagging for quick and easy styling. The tool has an ergonomic, slightly rounded shape and is available in 2 colours - Black and White.

In conclusion, the GHD Platinum+ Professional Smart Hair Straightener is a great option for quick, hassle-free styling. It is highly praised by stylists thanks to its convenience, safety and functionality.

TRESemme Keratin Smooth

For lots of people, the money-quality ratio is among the most crucial things they consider when making a purchase. With that in mind, the folks behind TRESemme have come up with the 2066U straightening iron that boasts excellent tech specifications and an attractive price.

Compared to many other irons (even more expensive), the TRESemme hair straightener offers a quicker heat-up time. Actually, it's ready for use within 15 seconds. With that, it doesn't sacrifice the performance and ensures an efficient heat distribution across the entire plate surface. Thanks to that, this model is perfect for those who are always in a rush - you won’t have to wait long until your styler becomes hot and will be able to make your hair straight in just one stroke. The heat can be adjusted within three available heat temperatures (up to 230°C); the control buttons for that are conveniently situated on the side of the unit. So, you're less like to change the settings inadvertently during use.

The other thing that we like about this straightening iron is its rounded shape. Thanks to that, you can not only straighten but also wave and curl your locks.

Affordable and Robust

What is also nice about this hair straightener is that it comes including a special TRESemme Heat Protection Spray.

Plus, you get a pretty large bottle (200 ml) that will last for a few months.

Lastly, we'd like to say that this straightener is made of durable materials so it should serve you for long years to come. Besides, in spite of its lower price, the manufacturer's backed it up with a 5-year warranty, which proves the high quality of the product.

To wrap the whole thing up, the TRESemme 2066U is surely one of the best budget-friendly hair straighteners. It straightens gently and quickly. Plus, it heats up virtually in an instant, which makes it ideal for busy families that often get ready in a rush.

What Is a Flat Iron?

If you have unruly curls but want to have straight shiny hair with no frizz, there is a decision for you. A flat iron is an ideal tool for hair styling. It is perfect for turning frizzy hair into smooth and shiny. And, alternatively, this tool is also great if you wish to make loose waves for a new look.

How does it work? This magic tool solders the hair cuticles using the heat. Thus, the hair looks shiny and smooth. However, keep in mind that heat can severely damage your hair, hence you need to be extra gentle with it. In our flat iron review, you can find and learn more about the best models available on the market today. They vary in size, temperature range, and plate material to fit every need and budget.

And in case you want to have beautiful curls, we recommend you to pay attention to our selection of the best curling irons. Also, you may want to check our selection of the best hair dryers.

What Features to Compare

Plates Material

When choosing a flat iron, the most important thing to consider is the material of the plates or, to be more precise, the coating. Most flat irons that are presented on the market have either a tourmaline or ceramic coating. Ceramic plates are good and will get hot in an instant allowing you to style your hair almost immediately. What's more, they perfectly maintain the pre-set temperature throughout the whole use. With regard to the tourmaline plates, these work a tad bit gentler and will better suit owners of thin or weak hair. That said, both materials have proved themselves to be highly effective and safe in use so that they can be applied to all hair types without the risk of damage. Along with ceramic and tourmaline plates, you can find a titanium coating which is considered the safest option among them all. The only flaw: titanium flat irons are quite expensive and will cost you several times more than an average deal.

Plates Size

Another thing to consider is the size of the plates. They can be narrow, measuring in up to 1 inch, and wide, more than 1 inch. The former works wonders straightening thin hair, short hair, and fridges while the latter will allow you to quickly style thick locks, adding to the convenience of use and saving you lots of time.

Thermoregulator

A thermoregulator is an important feature in a flat iron, especially if your hair is prone to splitting and fraying. It can be of two types: mechanical and electronic. Mechanical thermoregulators are very simple in use; however, they do not allow selecting the temperature with one-degree precision as electronic thermoregulators do. Flat irons with an electronic thermoregulator offer a greater multitude of settings, enabling you to choose from the range of 240°F to 450°F. As a rule, they feature LCD screens or a marked dial and allow customising the heat. The general recommendations say: if your hair is thin, use a flat iron on low settings, and if you have unmanageable strands, you can use a high heat mode.

Extra Options

Finally, pay attention to extra options. By this, we mean the heating speed - some models heat up in 30 seconds while others need only 10 seconds to reach the max heat; whether the flat iron has an auto shut-off function allowing you to prevent fire hazards; heat-resistant gloves for comfortable and safe styling; a bag for storing a hot tool, a stand or mat for convenience of use, and more. Such little things as indicators can make a difference too, so make sure to learn what accessories along with a flat iron come in the package before making a final choice.

Did you know?

All the owners of frizzy unruly hair try different ways to keep it a bit under control. With the invention of the straight irons, the life many people became so much easier because now they can rock a smooth silky hairstyle every day. Flat irons can straighten your locks and make them look longer and shinier. However, every rose has a thorn, and such styles are not an exception. Since flat irons use heat to straighten your locks, they can cause a lot of damage to your hairdo. That’s why we decided to share a few tips on how to keep your hair strong and healthy even if you straighten it every day.

Purchase a “soothing” shampoo

Even though such a solution won’t make your hair perfectly straight, it still can leave some positive impact. It adds moisture to your hair and makes it less unruly, thus prepares it for the straightening. You can also try straightening shampoos. They may have a better effect in smoothing your hair out, but they may not be suitable for all hair types. Plus, no shampoos can compete with results the iron gives you.

Always use a conditioner

We are sure there is no need to tell you about all the advantages of using additional hair care products like conditioner or moisturizer. However, we want to stress how important it is not to skip them in your routine if you straighten or curl your hair. Conditioning your hair will nourish your hair and make it look much stronger and healthier even amid the effect of the heat.

Never iron wet hair

Sometimes in a rush, we can break a few rules, but this one is an exception. Never, and we really mean it, never use a flat iron or a straightening brush on wet or damp hair. It can cause so much damage that you may have to cut your locks. If you are limited in time, use a hair dryer first. Although adding more heat to your hair may not like a very good idea, it is still nearly as dangerous as using an iron directly on a wet hair. Some people, who have very strong locks that are hard to straighten, have to use a hair dryer and a straightener each time they style their hair. There are some models of straighteners that are suitable for wet hair, however, their safety is still pretty questionable.

Always use a heat protector

Before straightening your hair, no matter if you are going straight for the flat iron or use a hair dryer first, apply a heat protector. As the name suggests, this product protects your hair and helps to keep it healthy and shiny.

Invest in a good device

No matter how tempting the desire to purchase the cheapest product may be, we recommend investing in a high-quality hair care device. There are many blow dryers and flat irons that use various technologies to reduce the damage your hair gets. Flat irons are completed with plates made of different materials. so you can choose the safest one. They also come with a wide temperature range that allows selecting the perfect one for your hair type. Plus, you can find pretty decent models at a very affordable price.

Following these steps, you can keep your hair healthy and shiny even if you love styling it with the heat on a frequent basis.
