1. Wash, condition and MOISTURIZE your hair extensions every 2 - 3 days. The human hair extensions do not receive your natural scalp oils and so need to have moisture added every wash. If you don't moisturize your hair extensions they will become brittle and break easily leading to split and ratty ends.
2. Treat hair extension with respect. They will not grow back if you yank at them with a brush, burn them with the blow dryer, kill them with chemicals. Be nice to them - they cost a lot of money so make sure you get your money's worth.
3. Always brush out all knots before you wash your hair, swim, or sleep. Start at the bottom and work your way up slowly using a paddle brush.
Make sure you wash in between the braids to keep your scalp clean and free of bacteria.
