What Hair Extensions Last the Longest?

So, you’re finally going to spice up your locks with some hair extensions, eh? Awesome – welcome to the hair extension club. But wait – you just found out there are several different types of hair extensions, and you’re not sure which one’s right for you. Well, if you’re looking for ones that will last the longest, I’ve got the answer.

The longest-lasting hair extensions include fusion hair extensions and micro-link hair extensions. Both types of hair extensions can last up to four months with proper care. 

Are you in the market for the longest-lasting hair extensions? Then you’ve come to the right place. I’m going to share the two different types of long-lasting hair extension methods, along with the pros and cons of each. 

Long-lasting hair extensions, here we come!

What Hair Extensions Last the Longest? Top Two Picks

If you’re looking for extensions that last the longest, you’re not alone. After all, not everyone wants to hop into the salon chair every few weeks, which is the case for some hair extensions (like tape-in hair extensions).

For those that want to get the most prolonged wear out of their hair extensions, here are the top two selections.

Fusion Hair Extensions

First on the list is none other than fusion hair extensions, which are also referred to as pre-bonded or keratin hair extensions.

They’re given this name because the tips come already bonded with keratin glue. All the hairstylist has to do is section off your strands and melt the extension to your natural strand using a fusion hair iron. 

Fusion hair extensions are 100% safe and great for all hair types when applied correctly. They’re also impossibly lightweight and discreet, allowing you to comfortably wear your extensions in a variety of adorable styles.

However, the drawback is that the application time is very long – we’re talking three to four hours. Not only that, but you’ll need to be extra careful with these babies, especially when it comes to hot styling tools. The last thing you want to do is damage or compromise the bonds!

Micro-link Hair Extensions

Micro-link hair extensions are another popular type of hair extension with four-month longevity (with the proper care, of course).

Like fusion hair extensions, micro-link hair extensions are applied in strands rather than wefts (which is the case for certain types of extensions, including clip-ins and sew-ins). However, rather than heat, micro-links are applied by clamping a bead onto the natural strands.

The perks of going the micro-link route are that they’re much quicker to install compared to fusion, and there’s no heat involved. They’re long-lasting, easy to take care of and blend seamlessly, allowing you to style up your hair however you please.

The drawbacks? Well, micro-links aren’t always the best option for all hair types. Those with thick and unruly hair may struggle with the tiny beads. A professional must also apply them to reduce the risk of damage.

How to Care for Extensions to Increase Longevity

Fusion and micro-link hair extensions can last up to four months – but that’s not without proper care. Without adequate maintenance, you likely won’t see past the three-month mark, which kind of ruins your hunt for the longest-lasting hair extensions.

Here are a few quick tips to make sure your extensions last a long time:

1. Use the Right Products

Listen, you don’t have to switch up your hair care products – but I highly recommend you do. Salt and sulfate-free shampoos and conditioners are best for all types of hair extensions. 

2. Don’t Overwash

Washing too often can loosen the bonds and cause your hair extensions to dry out. Yuck. That said, drop your washes down to once or twice per week. Oh, and make sure you’re using the right shampoo and conditioner, as mentioned above.

3. Detangle with Care!

Even the best and priciest hair extensions will end up tangling after some time. The best way to combat this is to brush your hair twice daily. Make sure you’re being remarkably gentle, and avoid the bonds. The last thing you want to do is accidentally snag them!

4. Use a Deep Conditioning Hair Mask Weekly

Hair extensions are meant to be smooth, soft, and silky. Are yours turning into a dried-out and frizzy mess? Then you need to “bring them back to life” ASAP. And the best way to do this (and combat future dry spells) is to use a deep-conditioning hair mask weekly. Keep it away from the bonds!

5. Limit the Use of Hot Tools

Too many hot tools are going to cause big trouble for your hair extensions (the bonds and the faux strands). That doesn’t mean you have to ditch your hot tools entirely (hello, I can’t live without my heated styling tools!) – just limit it and always use a heat protectant.

6. Detangle While You Sleep

Uh, what? Yep – you read that right. You need to be proactive while you sleep, as plenty of tangles and mats occur while you slumber. The best way to do this is by braiding your hair before sleeping (on your silk or satin pillowcases, of course).

7. Separate the Bonds

Did you know that your bonds can get grouped together? This is a bad sign for your hair extensions. But don’t worry – by taking a few minutes out of your day to separate them, you won’t have to fear entanglement!


Now you know the two types of hair extensions that last the longest: micro-link and fusion. You even know how to make them last the entire four months! But before you go get your extensions installed, take a peek at these frequently asked questions!

What hair extensions are best and last the longest?

Since we already know which type of hair extensions last the longest, let’s take a closer look at the material you should be looking for. Always choose Remy human hair extensions. Remy human hair has the cuticle intact, ensuring an all-natural appearance that’s unbelievably soft and silky.

What are the most durable hair extensions?

The most durable type of hair extension is fusion hair extension. After all, they’re glued directly onto your natural strands. So, it will be much more challenging to make them slip or come off. If you want durability, go with fusion hair extensions.

Can you get long-lasting hair extensions?

You can get long-lasting hair extensions! They’re known as “permanent” or “semi-permanent hair extensions.” They don’t last forever, but they’ll last a much longer time than temporary options, such as clip-ins and halo hair extensions, which need to be applied and removed daily.

Final Thoughts

For those who want their hair extensions to last the longest amount of time possible, fusion and micro-link hair extensions are the only way to go. They easily last up to four months (with proper care), so you don’t have to sit your caboose in the salon every few weeks. Winning!
