Ease of use 5.0 / 5.0

  • – Precise heat adjustment
  • – Beautiful eye-catching design

All this alone would be enough for us to crown the BioIonic OnePass our straightener of choice… But there’s more. The styler allows for precise heat adjustment, meaning YOU control the amount of heat that hits your precious locks. (Our pro tip: turn it down!)

We also award top marks to the look of this straightener. The luxe-looking dark grey of the styler compared with the baby blue plates is a complementary colorway that works wonders.

The curved barrel of BioIonic’s OnePass means curling and waving your hair is no problem at all. The silicon strips aid this function, making it one of the quickest tools for curling on the market. Once finished, simply brush out your curls, spritz with hairspray and dash out to your party.

4. GHD IV Styler Ceramic Flat Iron

Looks / Appearance 5.0 / 5.0
Ease of use 5.0 / 5.0
Functionality 5.0 / 5.0


  • – World-famous, trusted brand used in salons across the globe
  • – Advanced technology
  • – Multi-styling capabilities
  • – Automatic shutdown after an hour of inactivity
  • – Sensors that calculate hair porosity – kinder to hair


  • – Most expensive product on our list
  • – This exact product can only be shipped within the US (though other GHD products can be bought worldwide)

With its luxe gold plates and multiple awards to its name (from the likes of Company Magazine, InStyle and CoolBrands), this flat iron is instantly associated with premium functionality and being a worthwhile expenditure. But in the wrong hands, a truly professional tool like this can spell disaster for your hair. Salon-trained stylists obviously know how to handle heat on different hair types; but everyday women buying straighteners often neglect to research the proper use for their hair.

The GD IV Styler reaches scorching temperatures of above 350°F – obviously this would burn your skin to a crisp if you were to touch it, so we need to apply the same precautions to our hair. Just because you can’t feel it, doesn’t mean huge amounts of heat damage isn’t being done to your tresses. It’s recommended that you drastically reduce this top temperature (even use less than 200°F if your hair is fine or almost-straight anyway), and coat your hair with protective spray before use.

Tips for Buying a Hair Straightener

Our flat iron straightener reviews go in-depth in all you’d ever need to know about choosing a product. We explain what it means for a product to feature ceramic plates; what exactly ionic technology does; and how far-infrared technology works. We recommend styling tools for girls with wild curls who straighten every day; and those with soft waves who like the poker-straight look every now and then.

Our guides will show you which iron is best for achieving multiple styling techniques, and those that are top of their range just for simple straightening. We show you how to get the best straightening tech for your money, whether your budget is $30 or $300. We feature the biggest brands and compare them to those you’ve never heard of (but should!).

These are only a few things you should bear in mind when choosing a styling product to purchase. No matter what brand, model, or material you go for – our #1 top tip is to ALWAYS use a heat protection spray or cream on your hair before using heat! No matter what fancy coating is added to the plates that promises the utmost heat protection, remember that your skin would be scarred if you applied the same heat to it. The same goes for your hair, and you should protect it as best you can when you curl it for a weekend party.

Here’s our hot tips to know before buying:

  • – Ceramic is best for fine/thin/damaged/dyed hair
  • – Titanium is great for people with Afro/curly/thick hair
  • – Sleek metal outer design makes straighteners great for use as a curler as well
  • – Ionic technology prevents static and frizz
  • – Infrared technology protects delicate outer layer of hair
  • – ‘Coating’ on product plates is likely to come off/stop working over time
  • – Best straighteners have advanced heat control settings (so you can set it to a low temperature and prevent heat damage)
