Whether you're looking to go a little longer or just to change up the color of your hair, extensions are one way to try out a style without a big commitment. Among the options for applying the extensions is the glue-in method, which typically allows extensions to stay in for up to two weeks. While the application seems pretty straightforward, there are some things you can do to maximize the life of your new locks.

Wash First

Glue-in hair extensions typically last about 10 days to two weeks -- not long for the amount of work you may have to put in to get them. Since washing your hair often -- if at all -- is not recommended while you have glue-in extensions, be sure to wash and dry your hair well before you start. Do not use conditioner or moisturizer, as these products can contain oils that will end up making your hair oilier. When you get oily, you'll be tempted to wash your hair -- which will shorten the life of your hair extensions.


When you're applying the glue to the extension, you can use the bottle that the glue came in to squeeze the glue onto the weft -- or you could squeeze the glue into a syringe and then apply it to the weft. The advantage of using a syringe is that you'll get a more precise line of glue. While this may seem counterintuitive -- since you may think more glue would make the extensions last longer -- it can actually help extend the life of the extensions. When the glue starts to get mucky after a week or so, less glue on the weft will cause less itching and irritation and potentially keep you from wanting to remove the extensions.


If you're using human hair extensions, heat can be a big help in applying the glue and getting it to stay. Once you've glued the weft and applied it to the hair, turn a blow dryer -- on lower heat -- toward the weft. This can help the adhesive set faster, and allow you to go about your day without worrying whether your glue is dry.

After Care

What you do afterward can make a big difference in the life of the hair extensions. First, try to avoid washing the hair if at all possible. If you need to use hair products, The Complete Peruke Guide website recommends using a water-based product, as opposed to an oil-based one. To tell which is which, look at the ingredients listed on the bottle; if water or "aqua" is listed before oils, it's likely a water-based product. Additionally, use a wide-toothed comb that will prevent you from pulling out the extensions.
