To avoid damaging the hair extensions, the cuticles and your scalp, only wash with warm water. Use an Organic and sulfate free shampoo to avoid drying the hair out. Wash the hair gently in a downward motion with your palms. Never scrub or bunch the hair together as this will cause open cuticles to rub against each other causing friction. Rinse between each wash, and wash only 1-2 times. Gently apply 2-3 drops of natural oil over the hair while it is wet, and these oils will penetrate the cuticles and add moisture to hair extensions. Finally, lower the shower head and rinse your hair (not scalp) with cold water. Let your hair air-dry at home.
