First of all, let’s talk about the definition of hair extensions. Hair extensions are defined as additional hair pieces adding more lengths, volume, or highlight colors to the wearer’s natural hair. Compared to wigs, using hair extensions is a much more affordable and accessible choice, as hair extensions often have lower prices. Furthermore, natural-looking hair appearance is also a guaranteed feature when using hair extensions, as they only serve as a complementary piece, adding colors, length and volume to the original hair but not completely overshadowing the hair’s natural beauty.

The available 18 inch hair extensions in the market can be divided into wefts & closure, and tip & tape hair:

1.1. Wefts & Closures

Hair wefts are one of the most popular products worldwide, and the Mexico market is no exception. For hair wefts, the hair strands are sewn collectively into a single strip of hair, before being folded and taking the form of a hair bundle. For usage, hair wefts are often utilized in performing the traditional sew-in method, in which the product will be directly woven into hair braids as sewing base by a special needle, creating a long-lasting hair look. Hair wefts can be further divided by the percentage of long strands in the bundle: Single Drawn 40-45% long strands, Double Drawn 60-65%, Super Double Drawn 80-85%, with their respective purposes. For example, Single Drawn hair is best for layered hairstyles, or tight curly textures like water wave, Burmese curly,… while Super Double Drawn with its optimal thickness, is best for sleek, simple textures like straight, body wave, to further elaborate its elegance and style. Double Drawn, being the safest option, can fit a wide range of styles and textures, as it is the perfect balance of the other two types.

Closures on the other hand, are 100% hand-tied products, in which each singular hair strand will be hand-crocheted into small knots on a sheer lace base, making the closures a delicate hair extension product. However, this also renders the closure perfect as a full-coverage hair piece that can conceal the unwanted flaws like the balding hair spot or the weft’s sewing lines on the top head area. Furthermore, the thin, invisible lace base also helps the closure to blend in seamlessly into the user’s natural scalp, creating an effortlessly glamorous hair look.

Normally, for one full look, it would take 2-3 wefts and a closure, however, this ratio can change depending on the user’s personal preferences. Using the traditional sew-in method, the wefts and closures can be attached to the hair and stay there for a long time, usually  more than 12 weeks, making it the perfect choice for those aiming for a long-lasting, durable and sustainable hair style.

1.2. Keratin Hair extension

Keratin hair extensions are much more prominent in the Latin American hair market, thanks to their ability to deliver the most natural, effortless hair look, pleasing the popular beauty demands and standards among the female population in this region. Most of this product line are heat-activated products, as the keratin head on these pieces can be melted and used as an adhesive, attaching the piece onto the user’s real hair. In the market, there are two most popular choices of keratin bonds:

• Tip hair extensions come in several popular variations such as I-tip, U-tip, V-tip,… each named after the shape of their keratin bond at the tip. Except for the traditional installing method which involves using heat sources, like the styling iron to melt and attach the adhesive, some I-tip extensions can be applied using a no-heat method, where the hair is crocheted through small micro rings placed in the tip.
• Tape hair extensions, on the other hand, are typically sold in small, flat wefts, instead of in numerous versions like the Tip hair. Unlike Tip hair, Tape hair uses a strip of double-sided adhesive tape at the root, and can be pressed directly onto the natural hair once the release liner is taken off, making the application quick and easy, no heat or tools required.

Both Tip and Tape hair serve as a more convenient alternative of the traditional sew-in wefts and closures, as it only takes a few minutes to be glued or crocheted into the user’s original hair, applying subtle, natural-looking volume, length and highlight colors without any sign of bulkiness.

Normally, 18 inch hair extensions belong to a highly flexible hair length, most suitable for both short and medium-length styling. In fact, you can advertise this hair length as a versatile hair extension piece, as it can work with numerous styling, and face shapes.

The highest-quality 18 inch hair extensions in the market are often made of human hair. Based on their signature traits, human hair extension products can be divided into the two most popular options:

2.1. Virgin 18 inch hair extensions

Virgin human hair belongs to the higher-end product line in the market, offering supreme hair quality to luxurious, exclusive hair brands. This is due to its rare, pristine hair state. In fact, Virgin hair is strictly collected from 1 young donor only, whose hair must be untouched by any prior chemical involvement, hence, explain its integrity, immaculate quality and rare supplying sources. Being collected from one single donor also means that the hair’s cuticles are 100% intact and aligned perfectly, an important factor determining the hair’s quality. In fact, intact cuticles can help the hair to preserve its moisture, reflect light, hence, creating optimal hair health, delivering softness, natural sheen and durability. In reality, Virgin hair can be kept for 5 years and more under proper care.

Furthermore, cuticle alignment also delivers versatility. In the hands of stylist, Virgin hair can take on repetitive styling, as well as be bleached to as bright as #613 bright blonde.

2.2. Remy 18 inch hair extensions

Remy hair is the more economical hair line, promising both affordability and quality. It is initially collected from 2-3 young healthy donors, therefore, it can still preserve fully intact cuticles, displaying soft, silky, strong hair strands. Under good care, Remy hair can still be used for 2-3 years, which strongly showcases the hair’s durability and strength. However, being collected from several heads also means that Remy hair’s quality might be slightly inferior to the standard Virgin hair, as it lacks uniformed cuticle direction needed to ensure maximum functionality. Nevertheless, Remy hair can still be dyed and bleached to warm colors like the honey blonde #27.

Depending on the unique characteristics and advantages of each hair type option, hair business owners can decide which selection is best suited for their target market and clientele. For instance, Virgin hair, with its top-tier quality and performance, is ideal for high-end brands aiming to uphold their luxurious and exclusive product lines. In contrast, Remy hair is a smart choice for cost-conscious entrepreneurs seeking to deliver desirable quality at a more reasonable price.

The famous 18 inch hair extensions are the highly in-favoured products of numerous buyers, due to its functionality, and natural appearance. Sensitive to this highly lucrative product line, many hair vendors have attempted to get a fair share of this cake.

International hair vendors are often ones with long operation time in the business, with a strong business foundation and a wide customer range. Their business scale is further backed by their direct manufacture of the products, hence offering 18 inch hair extensions in wholesale price and large quantities, attracting a vast number of loyal big-buyers. Based on nationality, they can be divided into: Chinese, Vietnamese, and Indian hair vendors.

3.1. Vietnamese hair vendors

Vietnamese hair has earned a worldwide reputation of being the finest in the market, admired for its silky appeal, natural shine, and durability. In fact, these desirable traits are the result of Vietnam’s unique combination of environmental, genetics and cultural factors. Recognizing the value of such a huge advantage, Vietnamese hair suppliers have tapped into the local hair source by building their factories adjacent to it to maintain control over quality and authenticity, as well as reduce the unnecessary expenses. By fully engaging in production, Vietnamese vendors are able to deliver high-end human hair products at highly competitive wholesale prices, winning the hearts of many hair sellers across the globe.

3.2. Chinese hair vendors

As some of the earliest and most experienced industries, Chinese hair vendors have built a stable foundation and reputation throughout the decades. Such an extensive history has helped them become a prestigious supplier in the industry, attracting a wide international customer base. Over time, they have been able to introduce advanced techniques and machine-based systems to the industry, speeding up the production process and improving productivity. However, the new shift toward mass-production has led to a degradation of the overall product genuinity. This, along with the rise of unethical scams from within the market has negatively affected the credibility of Chinese suppliers.

3.3. Indian hair vendors

India is home to one of the largest hair industries in the market in terms of product availability. In fact, Indian hair vendors possess such a large hair source that they are even able to supply their signature Indian hair to many Chinese hair vendors. Indian hair vendors have two main hair sources: Temple Hair and Hair Balls. Temple hair, much like its name, is collected from temples after religious practices of cutting hair in exchange for fortune, while Hair Balls are collected from unsanitized hair trash in public places. Therefore, while shopping from an Indian hair vendor, clients always need to be extra careful of the product origin to avoid purchasing the low-quality Hair balls by mistake.

While shopping for 18 inch hair extensions in the market, shady hair suppliers and low-quality products remain a serious threat to businesses. Therefore, it is crucial for all buyers to be aware of the following signs of scammers to avoid falling victim for their tricks:

4.1. Unclear policies

Unclear, confusing policies are often the first sign of an unreliable vendor. A commonly-practiced tactic of many shady hair businesses is using misleading, extravagant word-use in their policies to confuse and overwhelm their clients. When confronted, they would proceed to give vague, unclear explanations or promises of the product’s quality and profitability. However, after the customers receive the extensions, which often arrive faulty or defective, and make complaints or request refunds, the scammers would just simply put the blame on the clients for “not understanding the policy thoroughly” and escape responsibility swiftly. Or worse, they would have no policies at all, so the customers would have nothing to protect their rights in the transaction.

Another scheme is to include unclear, hidden restrictions or fees such as: offering 100% refunds, but only if the package is returned unpacked and undamaged; or accepting deposit, but the deposit would be unreturnable under all circumstances,… so that the clients may feel that they are protected and have more confidence in purchasing. However, these are rarely made to support buyers, rather, they are just tactics to confuse and exploit them.

4.2. Product quality

As mentioned above, most high-quality 18 hair extensions are human hair products, hence, any other variations like non-remy, synthetic, mixed hair are often inferior and should be avoided at all cost! In fact, these alternatives belong entirely to a poorer-quality product line, with hardly any desirable traits like durability or functionality. Synthetic hair for example, are strictly made of plastic, brittle fibers with inauthentic, awkward physical appeal and hair sheen, and non-remy hair is an extremely low grade of human hair, collected from multiple unsanitized, processed sources, making it more prone to breaking and tangling.

Unreliable vendors might mask this truth by stealing reviews, feedback or visual presentation from other honest competitors and claim them as their own to appear more trustworthy. Hence, their social media content might seem non-uniform and inconsistent, and more like random videos and photos that they initially collected from other sources rather than their own authentic work.

Another widely-used method is to urge their clients into buying by time-limited sales or deals, to create buying incentives and encourage quick purchases before the clients have any suspicions about the products.

4.3. Using unofficial payment methods

Official payment platforms often have their own protective policies to keep away scammers and risky money transfers. For example, Paypal users can file for a refund or return on the app if their package arrived damaged, for the products are far too different from its initial description. Scammers are strictly prohibited from these platforms, so they have to resort to other suspicious, unofficial payment methods like through a shady payment link, wire transfer, or through a middleman. Making a payment from these methods does not only cause potential financial losses, but also a serious information leakage.

4.4. Inconsistent product knowledge

Experienced, authentic hair vendors must have an adequate amount of knowledge about the products and the market they’re selling their products for. They must be able to tell the differences between Virgin and Remy hair, the hair’s bleaching ability, as well as basic information about the hair’s treatment and care tips. As business owners participating in the demand and supply chain, they must also have certain insights about the market’s newest trends, or what the hottest items are, what the customers from a specific region are inquiring about the most,…

Any sign stuttered, unsure answers, or inconsistent explanations can be a sign of a scammer or an inexperienced vendor. However, neither of these types can be trusted, as their lack of knowledge and unprofessional work ethics could detrimentally affect your business image and customer satisfaction.
