You must have some questions if you haven\u2019t purchased hair extensions before. Everyone advertises easy to apply extensions<\/strong><\/a>, but it\u2019s not easy to buy them! Especially when it comes to selecting hair.<\/p>\n

Assuming you have already decided on the type of extensions you want, including length, the next thing that comes to everyone\u2019s mind is grams. We have had multiple clients who could not understand the meaning behind grams and were still confused about what to buy and what to avoid. Below, we have written a rather extensive guide that covers pretty much all the points of hair extension thickness and your hair health.<\/p>\n

If you are still unsure, don’t worry! Feel free to message us; we will be more than happy to help you. Alternatively, another guide is linked in the post below, which goes to even more details.<\/p>\n

1 <\/span>What Do Grams in Hair Extensions Mean?<\/span><\/h2>\n<\/div>\n<\/div>\n

\"What<\/p>\n

A gram spec for hair extensions indicates the weight of one strand or a complete set.<\/p>\n

For example, assuming the extension’s weight is 100 grams and 100 strands in the package, that makes it 1 gram per strand. Simple. However, that does not help as we need to know one more thing.<\/p>\n

2 <\/span>Why Do Hair Extensions Come in Grams?<\/span><\/h2>\n<\/div>\n<\/div>\n

Our US-centric readers sometimes get weirded out by the specifications of various hair extensions. Why do manufacturers use grams instead of ounces in United States-based hair stores? The trend has started with Asian and Indian hair suppliers exporting large batches of hair to European countries. The rest followed, although since most continents use grams, it was a convenience. It was too late when businesses opened hair extension stores in the US. Everyone was using grams already.<\/p>\n

Also, comparing and creating hair extensions using grams is much easier. The overall list looks much cleaner compared to ounces. So, instead of 3.52\u201d hair extensions, we have 100 grams, a nice and even number!<\/p>\n

3 <\/span>What Does Hair Extension Weight Mean?<\/span><\/h2>\n<\/div>\n<\/div>\n

As a rule of thumb, the thicker the hair – the heavier it is. The hair extension weight indicates strand and overall hair thickness. For example, “1g \/ strand\u201d hairs are much thicker than those with “0.5g \/ strand\u201d spec.<\/p>\n

It is rather simple and applies to all but the clip-in<\/strong><\/a>, weft and flip-in extensions<\/a><\/strong>. <\/p>\n

Why? Because these do not come in strands but rather wefts.<\/p>\n

4 <\/span>How To Choose The Right Hair Thickness<\/span><\/h2>\n<\/div>\n<\/div>\n

\"How<\/p>\n

While everyone would initially want to have the thickest hair possible (2g \/ strand), that is not the correct answer. The optimal weight of hair extensions is around 1g \/ strand! Unless you want to risk your hair falling out, constant pressure on the scalp, and headaches.<\/p>\n

There are always exceptions, as women with thicker natural hair can handle heavier extensions. To give you a rather short answer:<\/p>\n

0.5g \/ Strand Hair<\/h3>\n

These strands will fit just fine for anyone who has thinner hair. Choose this option to increase the hair length but not the volume. Otherwise, feel free to experiment and proceed with the next weight category below.<\/p>\n

0.7g \/ Strand Hair<\/h3>\n

We are getting to the fine to medium hair thickness category. It is a great choice for women wanting hair extensions to look natural while still lifting their whole look to a new level.<\/p>\n

1g \/ Strand Hair<\/h3>\n

Since a lot of females have medium-thickness hair (even though they believe otherwise), this is the most popular option. In other words, it\u2019s perfect for pretty much everyone but the Brazilian or African American<\/strong><\/a> women. If you are unsure, this is your pick.<\/p>\n

1.5g \/ Strand Hair<\/h3>\n

This is your only option if you want to go to extremes or have thick hair. Your hair will look as gorgeous as in a fairy tale. What if you have thin strands or thinning issues? There is an alternative for you, too: the double-drawn hair extensions<\/strong><\/a>. You get thicker hair at the most crucial parts without increasing strand weight.<\/p>\n

5 <\/span>What\u2019s the Best Hair Extensions Weight?<\/span><\/h2>\n<\/div>\n<\/div>\n

\"Whats<\/p>\n

It\u2019s easy to measure the thickness of hair extensions when it comes to strand-by-strand methods, but what about wefts? Surprisingly, it is somewhat similar.<\/p>\n

Less than 100 Grams<\/h3>\n

Like strands that do not exceed the 100-gram limit, these wefts will fit fine with pretty much anyone with fragile hair. Likewise, if you have medium-thickness hair and proceed to apply sets below our recommended weight, your hair will look skanky.<\/p>\n

100 to 160 Grams<\/h3>\n

This is the ideal hair weight for most women. Extensions with this spec tend to blend perfectly, naturally increasing both volume and length. It\u2019s also important to note that 18\u201d extensions at 140 grams will be thicker than 30-inch extensions of the same weight. We covered that in the guide above, so please read before buying.<\/p>\n

180 to 200 Grams<\/h3>\n

Like strands, these are for hair divas that want to have so much volume that it looks like you are out of this world. Or if your hair is already very thick and voluminous. Hair suppliers will always try to top things with 300g or even 400g extensions, but that’s too much weight to handle. Don’t take that risk.<\/p>\n

6 <\/span>How Many Bundles or Strands of Hair Do You Need?<\/span><\/h2>\n<\/div>\n<\/div>\n

So, you know the grams, and you know what they mean. Now, what about the actual hair extensions? How many bundles or strands do you need? As a rule of thumb, we suggest using around 150 grams of hair, which will be enough to cover your entire head.<\/p>\n
