1. Use a conditioner every time you wash your hair. The 909 Conditioner is specially made for extensions to help keep them soft and detangled. If this conditioner is too heavy for your hair there are two other conditioners that I recommend: Joico moisture mask and It's a 10 conditioner. I recommend combing the conditioner through your hair with a Wet Brush when you wash it, start at the end and work your way up while holding the base of the extensions to relieve tension on your scalp while combing tangles out.
2. Always use the Wet Brush to distribute a Leave-In Conditioning Spray and a serum through your hair after you are done with washing. This will Keep your hair from getting dry and brittle. My Favorite sprays are It's a 10 silk express, It's a 10 plus keratin and my favorite serum for extensions is Paul Mitchell Super Skinny.
