These extensions are created with real human hair, so it is entirely possible to color it to a desired shade to match your own hair, as well as to style it and wash it as you normally would with your own hair. If you pull on a single strand of hair and it comes out very easily, your hair will probably not be able to support hair extensions.
If you decide to have extensions attached, you have to care for them properly to ensure that they last. Hot fusion utilizes glue or keratin protein and attaches the extensions using a heating tool. Permanent extensions can be fairly expensive, on average they cost anywhere from $700 to over $1,000.00. Another consideration is that your hair and scalp should be relatively healthy before you try to attach hair extensions. Cold fusion attaches the extension with keratin bonds and does not use heat.
Many people who have thin hair use this method to increase the volume of hair, while creating a natural look with extensions.
Improper care can cause the bonds to weaken and to come loose from the natural hair.
It can take over three hours to properly "install" the extensions by a certified professional stylist.
Permanent hair extensions generally last about three to six months with proper care and maintenance. There are two methods of bonding, i.e, hot fusion or cold fusion. The extensions are attached with an application process called bonding where several pieces of hair is attached with a protein bond or a special glue.
