Types of Hair Extensions: A Complete Guide

Hair extensions come in 7 types: hand-tied weft, tape-in, sew-in (weft), fusion (keratin bond), micro-link (micro-bead), clip-in, and halo. Each attaches differently, has its own maintenance schedule, and carries a different level of risk to natural hair. 
Of the seven, hand-tied weft has become the most requested professional method, and the one we built IBE® around.

The 7 Types of Hair Extensions (Quick Comparison)

If you're short on time, this table covers the essentials. We go deeper on each method right after it.

These cost ranges reflect general industry averages for hair only and don't include installation. IBE® pricing depends on your stylist, the hair used, and your specific install. For a full cost breakdown, see how much hand-tied extensions cost.

Here's what's actually happening during each of these installs, and why the differences matter more than the marketing around them.

1.Hand-Tied Weft Extensions (IBE®'s Method)

What are hand-tied extensions?

Hand-tied wefts are extensions where the hair is hand-sewn, strand by strand, into a thin, flexible weft instead of machine-stitched into a thick track, a distinction we cover in more depth in our hand-tied vs. machine weft comparison.

That weft is then attached to a small horizontal row near the scalp. Hand-tied describes the type of weft; the attachment method on top of it is what separates one hand-tied technique from another, and that's where IBE® comes in.Invisible Bead Extensions® is our patented attachment method: a continuous beaded track that anchors the weft without the bead itself ever touching the scalp.

That distinction matters more than it sounds, since many traditional beaded weft methods rest the bead directly against the skin, which is usually where the scalp irritation people associate with "beaded" extensions actually comes from. IBE® was built specifically to remove that point of contact.

How is IBE® applied?

A certified IBE® stylist sections the hair and builds a continuous track using our bead-and-thread technique, placed so it carries weight evenly across the row instead of pulling at isolated points. Hand-tied wefts are then sewn directly onto that track, and because the tension is spread out rather than concentrated, clients generally stop noticing the extensions once they're in.

This takes real training to do well: every IBE®-certified stylist has gone through our certification program, which covers technique, placement, and tension in depth, not a single afternoon demo.

Pros and cons

Hand-tied extensions move the most like natural hair on this list and hold up well for clients who swim, work out, or wear their hair up. More detail in our hand-tied extensions pros and cons guide.

Pros:

• Lie flat enough to disappear in a ponytail or low bun
• No heat or adhesive; the only hardware is a single flat bead that never touches the scalp
• Wefts are reusable across multiple reinstalls when cared for properly

Cons:

• Installation takes two to five hours and requires a certified stylist
• Higher upfront cost than most other methods
• Move-ups every 7-10 weeks are more frequent than fusion or micro-link, though each appointment is quicker and reuses the existing wefts

Best for

Hand-tied suits fine and medium hair especially well, since the flat weft spreads weight evenly instead of pulling on isolated sections, and it holds up for clients who swim, work out, or wear their hair up.

2. Tape-In Extensions

What are tape-in extensions?

Tape-in extensions are pre-taped wefts, about an inch and a half wide, that sandwich a thin section of natural hair between two adhesive strips close to the root.

Pros and cons

Tape-ins are among the fastest professional options, though the adhesive is the method's main weak point.

Pros:

• Quick to install, often around an hour for a full head.
• Lie flat and can sometimes be reused for a second or third install with fresh tape.

Cons:

• Oil-based products, heavy root conditioner, and natural sebum can weaken the bond early and cause slipping.
• Tape can become visible in very fine hair as it thins toward the part.

Best for

Tape-in works best on medium-to-thick hair without significant chemical damage, since the adhesive needs healthy hair to hold securely.

3. Sew-In (Weft) Extensions

What are sew-in extensions?

A traditional sew-in starts with natural hair braided into flat cornrows that act as a foundation. A weft is then sewn directly onto that braided base with needle and thread.

Pros and cons

Sew-ins skip glue and heat entirely, which is their biggest advantage, but the braided foundation introduces its own trade-offs.

Pros:

• No glue or heat; avoids the chemical and thermal risks of fusion or tape-in
• Holds up well to regular washing

Cons:

• A fully braided foundation with wefts sewn on top can feel heavy
• Braids installed too tight can strain the hairline over time

Best for

Sew-ins tend to work best on thick, coarse, or very curly hair, which can support a braided base comfortably. They're generally not a fit for fine hair, where braiding alone can cause tension and breakage.

4. Fusion (Keratin Bond) Extensions

What are fusion extensions?

Fusion extensions attach individual strands to small sections of natural hair using a keratin-based bond, melted into place with a heated tool. Each strand is bonded individually rather than in a weft, making it the most labor-intensive method here to both install and remove.

Pros and cons

Fusion gives the most seamless result of any bonded method, but the removal process is where most of the risk lives.

Pros:

Blends well in very fine partings; no weft, track, or bead to hide
Strand-by-strand application allows the most natural movement of any bonded method

Cons:

Repeated heat exposure during application can dry hair out over time
Bonds require a specialized solvent and real effort to remove
A rushed removal can take natural hair with it, which is why we recommend following a proper hair extension removal process regardless of method

Best for

Fusion suits clients with thick, healthy hair who want strand-by-strand realism and don't mind a longer removal process down the line.

5. Micro-Link (Micro-Bead) Extensions

What are micro-link extensions?

Micro-link, also called micro-bead, attaches small sections of extension hair to natural hair using tiny metal or silicone-lined rings, clamped shut with pliers. The hold comes entirely from the clamped ring. Since fusion and micro-link are the two most common individual-strand methods, we put them head-to-head in our microlink vs. fusion breakdown.

Pros and cons

Micro-link skips heat and glue, but the rings require consistent upkeep to stay clean and secure.

Pros:

• No heat or adhesive
• Rings open relatively easily for removal

Cons:

• Rings sit directly against natural hair and can tangle or slide if not maintained
• As hair grows, rings shift from the scalp and become more visible
• Full reinstall at 3 to 4 months means every ring gets redone individually

Best for

Medium-to-thick hair tends to suit micro-link best, since fine hair can struggle to hide the rings once they've moved away from the root.

6. Clip-In Extensions

What are clip-in extensions?

Clip-ins are wefts with small pressure clips sewn along the top edge, made to snap onto sections of natural hair and come back out at the end of the day.

Pros and cons

Clip-ins are the most DIY-friendly option on this list, with no installation required and no ongoing upkeep.

Pros:

• No long-term commitment and no maintenance cost
• Fully removable at home in minutes

Cons:

• Daily in-and-out wear creates repeated friction at the same points, which can cause breakage over time
• Clip line tends to sit bulkier than semi-permanent methods, which can show in fine or short hair

7. Halo Extensions

What are halo extensions?

A halo extension is a single weft attached to a thin, flexible wire that sits across the top of the head, hidden under a small section of the wearer's own hair. Nothing is clipped, sewn, or bonded to individual strands.

Pros and cons

Halo extensions are the lowest-risk method here, since nothing attaches directly to individual strands.

Pros:

• Very little risk of damage; weight sits on the wire rather than on individual hairs
• On and off in seconds with no tools needed

Cons:

• Daily wear can cause some friction where the wire rests on the hair
• Wire can be hard to disguise in very thin or fine partings
• Not built for all-day, every-day wear the way semi-permanent methods are

Best for

Halo extensions are a good fit for most hair types looking for an occasional length or volume boost, particularly for events or special occasions rather than daily wear.

How to Choose the Right Type of Hair Extension

The right method usually comes down to hair type, lifestyle, and budget. Here's how the seven sort across each.

Final Thoughts

Every type of hair extension on this list solves a real problem, just not the same one, and not always for the same hair or routine. If low damage, natural movement, and the freedom to wear your hair up matter most, hand-tied extensions installed with the IBE® method remain the most requested option, for good reason.
