How long do hair extensions last?

The length of time that hair extensions will last varies from person to person. However, with proper installation, care and maintenance, your hair extensions should last you at least a year. Our hair extensions are made from the highest quality 100 percent virgin remy human hair. This means you’ll be starting out with the best, longest lasting hair extensions possible.

Improving the life of Hair Extensions

In order to get the most life out of your hair extensions, be sure to care for your hair properly by washing, conditioning and using the products that nourish it. We recommend using Dove Intensive Repair conditioner, One ‘n only Argan Oil moisture repair conditioner and oil treatment, Miracle 7 leave-in conditioner and Suave clarifying shampoo.

Caring for hair extensions

For frizzy hair, you can co-wash your hair (wash with just conditioner) every 2-3 days, spray it with John Freda Frizz Ease Dream Curls and comb it out with a paddle brush. This will extend the life of your curly hair by preventing frizz.

Finally, you will want to avoid alcohol-based products, sewing through the weft and sleeping with wet hair. Instead, use the products we recommend and be sure to allow your hair to air dry before going to bed. Taking these measures will allow you to get the most life out of your hair extensions.
