Co-wash hair extensions before your install. While conditioner is on the hair, detangle from the ends to the roots. (We recommend that your shampoo is 100% sulfate-free because sulfate can make your hair extensions fall out faster and easier). Also use natural or organic shampoos & conditioners on your hair extensions. Make sure you rinse with warm water, and rinse thoroughly until there is no product left on the hair. Let the hair air dry to it's natural state. At bedtime use silk or satin pillow cases, bonnets, or silk scarfs for best results...
