This term frequently appears on product labels and is used by skin-care experts but not always defined in simple, clear language. Here’s a quick explanation: If a product claims to be non-comedogenic it means that it shouldn’t clog pores or trigger acne — either by occluding the skin, blocking glands or irritating the hair follicle. The claim is not regulated by the F.D.A., however, and many companies do their own internal tests to determine whether a product should be considered comedogenic or not. (Some common known comedogenic ingredients are coconut oil and cocoa butter.) Typically, the fewer ingredients a product has, the easier it is to determine if it will cause any reactions.

Do diva straighteners turn themselves off?


In the world of dryers, it's a question of buying either the GHD Aura or the Dyson Supersonic. There's no question that Dyson's dryers are smarter. On-board CPUs receive information about temperature constantly, ensuring that hair damage isn't a factor. However, both GHD and Dyson are up to speed where it really counts: ensuring an even, rapid drying experience. Both use ionisation to dry hair quickly. The dryer from Dyson has a unique look that will seduce some people, but GHD's dryers are easier to customise via attachments. This contest will come down to personal taste.

Negative ions have been a longtime fan favorite in the hair care industry, and it is no surprise that this same technology would appear in our top picks for the best hair straightener. Negative ions have been found to reduce static and frizz while locking in moisture, and the same goes for your hair when you use the CHI Air Expert Classic Tourmaline Ceramic Flat Iron!


If your hair is plagued by tangles and knots on a regular basis (even in between straightening!), try switching your hairbrush out for a wide-toothed comb! The added space in between the teeth gently separately knots and tangles without the painful “Ouch!” with each stroke. If that still isn’t enough to tame your stubborn tresses, try a wet brush! These brushes are specially designed to work through knotted, wet hair without any tugging or pulling.
Cons: Low life expectancy. We only get 2-3 years out of each model. Their weak point is the rotating electrical connection. In older models, when the device starts losing connections, you could tighten the retaining clip in the connection, buying you another year or two of use, but the new connection is in a plastic housing that will break if you attempt to increase tension.
The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.

How long is GHD warranty?


For better or worse, we are B-U-S-Y nowadays. Running from meeting to meeting and trying to pick up our kids from carpool before soccer practice, it’s no wonder that we often place ourselves at the bottom of our daily priority list. This mindset typically carries over into our appearances and explains why more women than ever are rocking messy top knots and buns than ever before.
The nano ceramic plates in this straightener deliver far-infrared heat, a gentler alternative in and of itself. As if that weren't enough, there's also a reservoir where you can pour in some of the (included) argan treatment and thermal protectant, creating a conditioning steam that will strengthen and safeguard strands while you straighten. Admittedly an extra step, sure, but one that's well worth it.
These ultra-smooth plates are great for straightening stubborn strands like curls and waves and are also ideal for creating natural, finished curls (similar to a curling iron) and even beachy waves. By gliding effortlessly across hairs of all types, without pulling or breakage, the ISA Professional Titanium Flat Iron has the potential to leave your hair looking and feeling healthier after each use.
If you are unsure what exactly your hair type is (or if it has changed over the years, which happens more often than you’d think!), check out this incredible overview by the hair professionals at Redken! Don’t stress if you have combination hair (i.e., fine and curly or thin and straight) either; we recommend choosing a hair straightener based on your biggest hair complaint and focusing on that problem first. So, if your curls are driving your nuts, you will want to select a hair straightener with higher temperatures, thin hair needs moisture, etc. You’ll find that your entire hair type can usually benefit from the extra TLC!

If you are at a loss for what you can do in just one minute, check out this list for a little inspiration:
