In order for you or any customer who is following this article to better understand the number 18 inches, we convert it to other length units such as centimeters, feet, and hands as follows. 

  • 18 inches = 45.72 cm = 1.5 feet = 4.5 hands

Of course, length is only for straight hair. If you want to measure for curly or wavy hair, you will have to straighten your hair first. 

As mentioned, an 18 inch hair extension has the same length as over 45 cm. At such a length, your hair is expected to reach mid-back. 

Another thing to note is that the hair extension can also be shorter or longer than the middle back depending on the height and body structure of the user.


Surely many consumers will wonder how much the weight of an 18 inch hair extension is. 

According to statistics, normally an 18-inch-long weft bundle will weigh about 100g. 

However, the design of each type will have a different weight. For example, with hairstyles that use clips or duct tape in the extensions, the hair is not grouped into bundles but instead into separate small sections. 

In the end, the total weight is not the same. You can refer to the weight list of many suppliers for details. 

However, each supplier will have lists of weights for different hair extensions.

It is worth mentioning here that it is undeniable that price always goes hand in hand with quality. 

If a product has a clear origin, the hairdressing material undergoes a careful selection process, and the high price is understandable. Take Vietnam as an example, hair sources are from 100% natural hair of Vietnamese women living in the mountainous regions. In these places, they get the tradition to grow hair and then sell to the suppliers in order that they can have additional income. Almost all hair factories in Vietnam mainly provide products with 2 main qualities: Virgin hair and Remy hair.

China hair extension is one of the largest hair markets with a large production scale and high competitive advantage. 

It is worth noting that some products have the name of origin as China, but they do not necessarily originate from Chinese people donating hair. 

In fact, China’s hair-making materials come from only a small percentage of locals. It mainly comes from neighboring Asian countries like India. 

Due to the large scale of production and the large amount of imported hair for production, it is even more difficult to control the quality of hair sources and products. 

According to research, there are a number of hair factories in this country that treat hair with chemicals and mix them with synthetic hair to make the products more attractive, or even generate greater profits. 

China’s 18-inch hairpin used to be very famous for its diverse products and comparatively low prices. However, there are more and more competitors. 

In addition, instead of cheap prices, customers are paying more attention to the quality and durability of hair extensions. 

These effects require hair factories in China to carefully review and rethink the core value of 18 inch hair extension products.


India is also one of the earliest hair markets in the world. Can be said, the hair extensions industry in India is one of the most noiseless and business fields in this country. It has brought numerous profits for this country. 

18-inch Indian hair extensions come from 2 main sources: temples and income from hair donors. 

According to the beliefs of this country, it is believed that giving hair to the gods is a good act and you will receive support from them. 

So every year a large amount of hair comes from temples. Here, people will donate their hair to show their hearts to the gods.

However, the demand for hair extensions is increasing, it is even smaller than the supply. 

Meanwhile, the amount of raw materials from temples is not enough and cannot meet the demand for production inputs, so hair factories in India have to look for other sources. It’s mixed hair. 

Manufacturers will collect hair from many different places such as salons, and shops. Accordingly, most of the outer cuticles do not follow the same direction, making the hair tangle and unrecoverable.


What length should hair extensions be?

In general, it’s better not to wear your hair significantly longer than your natural hair length. 

Note that a maximum length of 3 inches to 4 inches more than your natural hair length would be the ideal choice. However, that also depends on your personal preference.

Can you put hair extensions in really short hair?

For the most natural results, your hair should be at least 4 to 6 inches long. 

This allows your real hair to cover the clips or joints of the extension. It also ensures a secure hold on the hair extensions.

Can you swim with hair extensions?

The answer is absolutely world.

Be careful not to leave your extensions in the water for too long and make sure to dry them as soon as you get out of the pool. 

Are clip-in hair extensions worth it?

Clip-in hair extensions are worthwhile for anyone who wants to change their hair style or appearance. 

They are also one of the least damaging to the user’s natural hair, as each clip comes with accompanying support from silicone bands to help prevent damage and discomfort.

Can you let hair extensions dry naturally?

The short answer is no.

The reason is that wet hair is much more vulnerable and damaged. That’s why you should use a hairdryer to dry your extensions and make sure you never go to bed with wet hair.
