The Pros and Cons of Long Hair Extensions

So, to make things easier for you, we did some digging around and came up with a brief yet valuable guide on voluminous hair extensions. Since the 2020s update, there are no greater lengths than those listed below.

If you want to go for the longest possible length, then Brazilian wefts (straight) is the way to go as they extend to up to 40 inches (or 101 cm).

If you want variety and try clip-in, tape-in or other hair extensions, then the maximum that we have seen someone offer is 30 inches (for tape-in) or 75 cm.

Update: Since early 2019, AiryHair now offers wefts of 40 inches! We did check and could not find any other company in the world that sells hair extensions that long.

Since 24” tresses already reach the tailbone, what about an even longer weft?

26” and 28-inch extensions will be just above the butt, assuming you are 5.4 Ft or 1.65m. However, if you want to curl the hair, the perceived length will decrease!

30-inch and 32-inch body wave hair wefts will partially cover your butt while curly locks will be somewhere above it.

34-inch and 36-inch hair extensions will reach the bottom of your butt!

38-inch and 40-inch hair extensions are best suited for tall women that want to enjoy the sexiness of long hair.

The advantages are easy to list!

  • First is the sexiness of the long hair, added desire, and whatnot.
  • Second is the freedom to style your hair in any way, shape, or form.
  • No, really, think about it. There is not a single hairdo or a hairstyle that you can’t pull-off.

However, there is one main disadvantage that everyone keeps on forgetting! Yes, we mean split and/or thin ends.

  • The longer the hair, the harder it is to maintain and keep these ends healthy. Unless we are talking about synthetic hair. Therefore, one should expect more split ends than with the 20” hair or hair extensions.
  • Upkeep costs are another con that one should consider. Washing long hair will require much more product and drying times will double!

What’s Our Advice?

So, you have made up your mind! Still, want to buy hair extensions and rock that insane look? In that case, you have few options:

  • To solve the split ends issue, cut the half-inch from your tresses and enjoy a much healthier look. Be sure to apply some oil afterward.
  • Consider double drawn hair, if the V-shaped hair does not look good on you. Please note that the costs are going to be much higher than of regular hair extensions.
