Here is an overview of the main applications that you will be offered so you won't be fooled by corporate naming

If you've never worn hair extensions before, you'll first want to choose the type of application or bonding method you'd prefer. It can be confusing comparing your options because many of the methods are similar but named after the specific product or company. Therefore two different salons may be offering the same method, but due to marketing the benefits and disadvantages are not clear. Here is an overview of the main applications that you will be offered so you won't be fooled by corporate naming.

Clip-In

If you're looking for temporary hair extensions without much of a commitment, clip-in pieces are a great place to start. These can be purchased at wig shops or beauty supply stores and come in a wide range of lengths, colors, and styles. In addition to buying the piece, you'll have to get some clips so you can attach them to your head. Sometimes these clips need to be sewn into the strands after which the extension is placed. Once set, it can be styled to appear more natural. It is recommended to have a stylist help you sew in the clips and arrange the strands if it is your first time.

Bonding/Fusion

This is one of the more common methods used due to the resulting longevity of the hair extensions. Human or synthetic material can be used and the strands are bonded with a glue-like adhesive (keratin in fusion) to the natural hairs. These can be used to add length, thickness, or just for a splash of color. If taken care of properly, fusion strands can last for up to 4 to 5 months, bonded with glue only lasts a week on average. However, excessive washing, brushing, or tugging can result in broken strands and a ratty appearance. To remove the bond, a solution is applied to it and then the hair extensions are slipped out. Damage can be caused where the bond was made, which may require a trim to restore the appearance.

Clamp

There are several different types of clamps that range in style and size, but most serve a similar function. The clamp holds several strands and is placed around the existing hairs. It is then clamped into place, often with pliers. The grip allows it to stay in place until growth moves it, at which point it can be repositioned a few times before it needs replacement. This is a good option for those who use little heat for styling. Too much blow drying or flat ironing can heat up the clamps, especially if made of metal, and result in burning.

Sewn

Women who want to avoid harmful glue or clamps may benefit more from sewn-in tracks. These can fully or partially cover the existing strands. With this method, existing hairs are braided to hide below the weave. The weave is then sewn in from side to side starting from the bottom up. As the roots grow, it will have to be adjusted. If done well, it can look undetectable, but it does feel lumpier to the touch.
