What Are Weft Hair Extensions?

Simply speaking, a hair weft is made up of various strands of hair that’s sewn to a cloth or ribbon material to form the weft. This type of hair extensions have become increasingly popular and are best known for being super versatile.

A lot of people prefer Weft Hair Extensions due to having them semi-permanently fitted by a professional in a salon. That way, you can take away all the fuss of having to style and apply Clip Ins every day however, that doesn’t mean they’re a walk in the park to keep looking their absolute best! 

Unlike Clip In extensions, you can’t just take them out if you’re not feeling the look or need to give them a little bit of love to brighten their appearance. They're a bit more high maintenance than that. Trust us though, they are so worth the investment, aftercare and when looked after properly can last up to 9 months or longer. We've had some clients have their hair last for well over two years.. & that's what you get for working with amazing hair! 

People tend to choose Weft hair extensions because of the full and thick bodied end result. If you opt for a weave we advise to visit the salon every 6 weeks to have them tightened and every 12 weeks for a refit. By doing so, you’re keeping your weft hair extensions in the best possible condition.

There are two main types of weft hair extensions - single or double. So without further ado, let’s get into the nitty gritty about them. 

What Are Single Weft Hair Extensions?

As the name suggests, single weft hair extensions only have one layer of hair to them. With this in mind, the weft will be a lot thinner and will be more beneficial to people not wanting the bulk and weight of a double weave.

Some people with thinner hair wouldn’t get the desired look and may be left underwhelmed with the impact boost that these have on their hair volume. Single weft extensions are incredibly popular with modern trends - after all, it’s the standard thickness that hair extensions usually come in.

The hairs used are varied, which creates a much more natural look for the client. By this, we mean that the lengths are a mixture of long and short. That way, there’s a more typical layered look to somebody’s haircut and it’s not obviously artificial.

Each strand of hair has a different growth rate, which means that each strand of hair will be a different length, that’s why single weft hair extensions are increasingly popular. The hair stays thick and prominent around the scalp and top of the head, yet tapers off nicely into a lovely finish towards the ends at the bottom.

They’re often cheaper than double, triple or even quadruple weft hair extensions too. If you’re looking for a super-voluptuous finish, you may be a little let down by a single weft.

Especially for those customers looking for an ultra glam look, as there’s only a single weft of hair, it lacks the deep layers which will add volume. However, single wefts are still more than capable of looking amazing! 


What Are Double Weft Hair Extensions?

Whereas single wefts are renowned for their various length hairs, the shorter hairs are replaced with thicker and longer hairs in double wefts.

Spectrum One Weaves are all double drawn, which means they’re the perfect choice for ladies and gents who like to go for an all-out glamorous look, adding serious volume to any hairstyle.

Double weft hair extensions are thick from root to tip. If you’re looking for an easy way to achieve a full-bodied look with your hair, then look no further. A double or triple weft is the perfect choice as the extensions are so thick, it means that you won’t have to purchase as many strands as you would if you were buying single wefts - meaning less maintenance and more convenience - a win win!

While you may be saving time with less maintenance and a more convenient choice, double weft hair extensions are naturally more expensive than single wefts. Quite simply, you’re getting more hair than a single weft, so it’s bound to be more. As they’re a lot thicker, they’re heavier in weight so while you may get fewer strands, you're still getting more hair. 


The Verdict: Which Is Better Quality?

Quality is always something that you should look out for when purchasing Weft hair extensions however before you can take quality into account, you need to find the right set for you. 

At Spectrum One we prefer a double or triple weft because we love the voluminous finish. Our 14” Weaves are generally double sewn and our longer 20” and 24” are triple sewn to give you the fullest and thickest look.

For an ultra glam and full-bodied hairstyle, double weft hair extensions are definitely the right choice for you however keep in mind that the quality will differ from brand to brand.


So as you’ve just read, there’s a stark difference between single and double weft hair extensions. You need to make sure that you choose the right product to suit your needs and requirements.
