Hair Extensions 101: A Beginner's Guide to Every Type

Shopping for extensions for the first time can feel like learning a new language. Wefts, tapes, clips, sew-ins. Every word sounds familiar until you have to choose one.

The good news is that nearly every option falls into four groups. Once you know how each one attaches and how much upkeep it needs, the decision gets a lot easier.

What are the main types of hair extensions?

The four main types are clip-ins, tape-ins, machine wefts and J tied wefts. Clip-ins go in and come out at home. Tape-ins bond to your hair with adhesive. Both kinds of weft are sewn in by a stylist. They differ in how they're installed, how long they last and how much upkeep they need.

Clip-ins: the no-commitment option

Clip ins hair extensions are wefted pieces with small clips sewn along the top. You snap them in, style your hair, and take them out at night.

That makes them the easiest place to start, especially for a special event or a trial run. JZ's 22-inch set, for example, includes 11 pieces with 23 clips in total, and with proper care it can last 9 to 12 months.

There are limits. The clips need enough natural hair to grip, so they aren't recommended for fine or thin hair. They also shouldn't be slept in.

Tape-ins: flat and low profile

Tape in hair extensions are thin pieces with adhesive already on them. A stylist sandwiches a small section of your hair between two pieces, and the tape holds it flat against the scalp.

Because they sit so flat, tape-ins are a common pick for adding length and body without much bulk. One pack holds 10 sandwiches, or 20 pieces, and a full head usually takes 2 to 4 packs. Expect to go back to your stylist about every 6 to 8 weeks so they can be moved up as your hair grows.

Weft weave extensions: sewn in for a fuller look

Weft weave extensions use a strip of hair, called a weft, sewn onto small braids or a track close to the scalp. The hold is secure, which suits thicker hair and bigger changes in length or volume.

This one isn't a home project. Sectioning and tension take skill, and a set that's too tight will let you know quickly.

Two kinds of weft are common.

Machine wefts. Machine weft hair extensions are sewn by machine into one wide strip, so a single piece covers a lot of ground. JZ sells them as a piece 25 to 27 inches wide, and 2 to 4 bags usually cover a full head.

J tied wefts. These come as pre-cut bundles. A bag holds 3 bundles, each about 12 inches wide. Because they're shorter, a stylist can place them section by section around the head.

Human hair or synthetic?

Everything above comes in human hair, and the material matters. Human hair can be washed, colored and curled much like your own. Synthetic hair costs less up front, but most types can't handle regular heat styling and tend to look flat or tangle sooner.

JZ Styles sells only 100% human hair, which is worth knowing if you're comparing brands.

How to choose

Start with your hair. Fine hair often does better with tape in hair extensions, while thicker hair can carry machine weft hair extensions or J tied wefts. Then be honest about how much upkeep you'll actually keep up with. If regular salon visits sound like a chore, clip ins hair extensions might suit you better.

Before you buy

• Check color in daylight, on clean, dry hair.

• Go up a pack if you're between sizes.

• Blondes often arrive warmer than pictured. A purple shampoo or a stylist's toner evens it out.

• Ask how a set will be removed, not just how it goes in.
