1. Getting to Know 18 Inch Hair Extensions

The biggest difference that 18 inch hair extensions have over other length variations is – of course – its length. By measurement, an 18 inch hair extension, when installed at your nape, will fall just below the shoulder blades. The result is a balanced – neither too long nor too short look similar to the natural, medium length that many women go for.

With such a popular length, no wonder why 18 inch hair extensions are selling like hotcakes. In fact, for hair businesses, this could mean more profit, and a wide range of benefits to cling onto: 

• The length itself is already a profitable trait. 18 inches is enough to create a visible transformation, without demanding extra maintenance. This means a more massive appeal – a safer inventory that promises to attract a larger number of customers.
• A stable, large proportion of customers are beginner extensions users with no prior experience in using extensions. To them, 18 inches is a safe length, providing as much versatility without demanding extra maintenance – perfect for brands to recommend as an entry-level, beginner-friendly product.
• Among the popular hair lengths, 18 inch hair extensions are also one of the most affordable lines. This makes them a more budget-friendly inventory option compared to longer, more expensive lengths out there. 

Therefore, when looking at 18 inches hair extensions – we are looking at a highly lucrative investment. Not only are they a safe, balanced and popular choice for customers, but they are also a highly effective and budget-friendly inventory, especially for beginner hair businesses. If you – as a seller, are struggling with inventory decisions, maybe this product line will be your answer!

2. BESTS of 18 Inch Hair Extensions

Product diversity is also another huge benefit when sourcing 18 inch hair extensions. In fact, to quickly meet the diverse hair market demands, many manufacturers have come up with new, innovative product lines. If you plan to start stocking this hair length, you should start with the most popular options just to be safe. These popular lines will be mentioned below: 

2.1. Hair Weft (Sew-in Extensions)

There’s a reason why hair wefts are mentioned first – because these are often the easiest to source and one of the most popular options as well.

A typical hair weft/weave consists of hair strands sewn into a strip and folded into one bundle. It is often used as a crucial ingredient used in the sew-in method, a traditional installation method of many African descents – the hair market’s biggest customer group.

On top of that, hair wefts are also highly sought-after as a base product to be customized into other advanced products – such as tape-ins, clip-ins, wigs,… Hence, for stylists, custom unit makers, these are an absolute must!

2.2. Clip-in Extensions

Next on the list are clip-ins – highly in favour for its convenience and beginner-friendliness.

Indeed, its construction consists of small hair wefts, with tiny, blending hair clips attached – allowing the piece to be attached within seconds only. This feature – hence, make clip-ins the most convenient type of 18 inch hair extensions, extremely suitable for everyday wear. 

This fast installation alone makes clip-ins a superior product line. Indeed, their fast installation and easy maintenance make clip-ins a crucial inventory choice – especially suitable for a huge proportion of buyers preferring a simple, everyday look.

2.3. Tape-in Extensions

Leaning more to the professional category – tape-ins are also one of the most highly in favour lines of on the market. Much like clip-ins, tape-ins would also feature lightweight, flat hair weft. However, instead of hair clips, these will be attached using a strip of tape at the roots, able to be glued to natural hair in just minutes. 

Among the available options on the market – tape-ins appeal to one of the broadest customer bases. Stylists are often its primary users, as tape-in installation is one of the highly requested salon services. However, tape-ins also sit well with a stable number of individual users, thanks to their fast installation and long-lasting results it provides. 

Therefore, if your brand plans to target both B2B customers (salon professionals, and B2C (end-users), selling tape-ins might be the first step of the masterplan.

2.4. Keratin Bond Extension

A salon-specific type of 18 inch hair extensions we must mention is the keratin bond extensions – one of the most advanced and seamless hair extension lines there is!

Its construction is quite unique – Keratin bond extensions are extremely lightweight hair pieces, with one end bonded with keratin. Upon installation, these ends would be melted and glued onto your customer’s hair, seamlessly blend into their hair volume, creating the ultimate natural look that many salon customers aim to achieve!

As lightweight as they are, keratin bond extensions are mostly sold in packs of 100gr – consisting of 25-30 pieces each. And, because these are strictly dependent on tools and professional help for installation – their primary clientele mostly include stylists, salon professionals only.

2.5. Nano Ring Extensions

Of all types of advanced hair extensions – nano ring hair extensions are indeed one of the most innovative and hairsafe options.

Its construction is quite similar to that of keratin bond extensions – lightweight hair pieces with one keratin bonded ends. However, instead of glueing to the strands, these pieces will be tied to the users’ hair using a nano ring or plastic tube – creating no heat or adhesive damage whatsoever.

Possessing both seamless blend and hair-safe application, nano ring extensions easily belong to a premium end of the market. For hair salons targeting luxury clientele, or customer conscious with hair health → this product line would be the most ideal option.

2.6. The Most Popular Types & Their Pricing

Different types of hair extensions come with different pricing ranges – after all, each of these options has their own production, sourcing requirements. Therefore, when shopping for 18 inch hair extensions, businesses should take into consideration these pricing gaps – and plan your purchases more carefully:

Types of Hair Extensions	Pricing range
18 inch hair wefts	From $70-86/100gr
18 inch clip-in extensions	From $50-80/100gr
18 inch tape-in extensions	From $50-65/pack
18 inch keratin bond extensions	From $45-62/pack

Expert Tips: However, please bear in mind that the prices mentioned above are not entirely fixed. In fact, when sourcing 18 inch hair extensions or any similar products – the final price will be affected by many factors. 

For example, ordering textured, colored hair equals more production that translates directly to higher unit costs. And, on top of that, density options, or hair qualities like Raw, or Virgin – also demand different levels of sourcing – hence, requiring different costs. Therefore, to avoid making the wrong decisions and let your money go down the drain- make sure to research your target audience and learn their patterns first.

3. Where Should You Start Looking

As a hair expert in this field, I am more than confident of my overall knowledge about the hair industry. And, one thing I have soon figured out – that I assume many of you are more than aware of, is that buying from manufacturers is always the better choice price-wise.

In fact, the prices mentioned above are from hair factories who produce their own. If you source from an importer – expect the price to be double, triple, or 5 times higher than that!

Not only price-wise, a manufacturer can also provide you with more assurance in terms of product quality. In fact, working with them means that you also have more control and inspection over the hair’s sources and output quality – providing you more confidence with the products.

3.1. Hair Sourcing Options You Can Consider

Speaking as someone who had too many days sourcing hair and working with buyers worldwide, I want to share one big good news: In the market, there are quite a range of manufacturers you can source from:

• Chinese hair vendors – well-known for their advanced production and high product diversity. If you are interested in sourcing the most trend-forward 18 inch hair extensions – this is where to start looking. However, brands might also need to be more wary, as there are many scammer threats in this hair industry. 
• Indian hair vendors – the cheapest and most widely affordable hair source there is! Indeed, this is the perfect place for beginner hair brands wanting a safe and budget-friendly start. However, their lack of product diversity might be a challenge for brands targeting trendy segments.
• Vietnamese hair vendors – the most authentic and high-quality hair source. This makes them the best source for those wanting ethically sourced and authentic human hair products. However, as follows, their pricing might be slightly higher.

Of course, these are not all there is. In the market, there is still a diversity of other hair sources like Burmese, Cambodian hair vendors. However, the three mentioned above are often the most widely-trusted options with larger production scale – making them a more suitable wholesale option for businesses.

3.2. How To Find Hair Vendors For Your Business

Unlike what people might assume, finding hair vendors is not impossible. In fact, in the era of technological development and social media, finding a suitable manufacturer is easier than ever – with the help of search engines, and other popular tools.

The quickest ways to get to a huge number of vendor options are often using search engines on Google, social media. Easy enough – you can search up specific keywords such as “wholesale 18 inch hair extensions”, and the result would reveal multiple vendor options up for choosing. 

If you find it hard to trust these online sources, you can also rely on recommendations to get connected with tested, trusted vendors. Next time you go vendor-hunting, maybe you can try asking for suggestions from your friends, colleagues, or from experienced business owners in workshops, public groups,…

If you have little source to ask from – worry not, you can still purchase these information by buying vendor lists. These lists can cost you from $0-1000+ – quite a necessary investment for hair brands struggling with finding the right vendors.
