Fusion – can be cold or warm fusion, link/lock fusion or fusion loops. This is where pretipped extension hair strands are coated with a chemical that "fuses" with your own hair when treated with an applicator gun. The extension can also be fixed using a l ring that is tightened around your hair strand and the extension strand to keep them attached. These are generally attached in a salon and may need to be tightened, if they become loose or removed(when finished with) by the stylist.

Bonding – This method uses a chemical or glue to attach a hair extension to your hair, usually strand by strand. The extension is attached close to the scalp. Most extensions can be removed using a a remover to dissolve the glue.. Some times acetone is used.

Lastly, the most important consideration when come to hair extension: Are you looking for a permanent or temporary hair extension style. A permanent hair style change usually means a number of visits to your salon to get the human hair extensions properly attached and regular appointments to look care for them after wards. The human hair extensions will need to be looked after carefully to keep them looking healthy, this can mean less frequent hair washing using a good conditioning type shampoo. A temporary hair style change can often be put in at home, the hair extensions taken out when not needed and reused as required.The most of hair stylers prefer to do temporary hair style,its help to be often put in at home and maintenance is very easy and deployed.
