Basic Terms

When you start looking at buying extension, you’re going to find a lot of new terms. So we’re going to go over a couple of the most basic terms you need to know.

Weft / weave hair from

The first term you’re going to encounter is wefts. A weft is a string of hair that you place in your natural hair. It can be of various lengths and widths and it’s usually not that thick. This is where hair extensions differ from wigs because you get individual wefts of hair that you can place in your hair where it suits you.

Remy Hair

The next term you might hear when you’re looking around is remy hair. What it really means is that the cuticles of the hair are all aligned in the same direction. The cuticle of your hair is the outside portion and it’s all these little shingles that lay on top of each other. So basically, when your hair is hanging in the right direction, you get all of these shingles that are laying properly, however if the hair wasn’t aligned so they’re not going in the right direction, if some hairs were upside down, they get locked together and then they start creating tangles. If you multiply that by a couple hundred strands of hair, you end up with one big mess of hair. And if you ever buy extensions or see people that have them with that problem, that’s usually what it is, it wasn’t all aligned correctly. So take that into consideration when buying extensions, it is always better to by remy hair, it will save you a lot of trouble.

Double Drawn Hair

This basically means that it goes through that process of getting the hair in the right direction and sorting twice. So they get all the cuticles aligned, everything looks good and then they go back and check their work one more time to make sure everything is perfect.

Finally, you’re going to see grams referred to a lot. Usually the weight of the extensions or the weight in grams that you see indicates how thick each different set it. It also depends on how long the extension is. For example, if you buy 30 inch extensions that weigh a 100 grams, it’s going to be a lot thinner than if you were to buy a 14 inch extension that weighs a 100 grams. So keep that in mind, anytime you go a little bit longer, it’s going to get a little bit thinner.

When we’re talking about grams, it’s important to know what to buy. Usually, within the 100-120 grams extension range, they’re going to be fine or thin hair extensions. That is usually the smallest amount a set is going to be and that’s best for fine or thin hair. If you’re going for length and a little bit of volume in fine, thin hair, then that 120 gram amount is usually the right amount. If you have medium thick hair and you just want a little bit of fullness, a 120 grams can be a great way to get that, just don’t for more than that. If you’re aiming for length and you have medium length hair, 200-250 range is recommended. It’s going to give you that extra volume and it’s going to match your natural volume.
