Shampoo and deep condition your hair extensions before you install it. We recommend Suave Professionals Shampoo and conditioner for our Brazilian Hair, and TRESSEME' Shampoo and conditioner for our Virgin Brazilian & Indian Hair. (Any kind, they have some for shine, softness everything! It's the bomb!)
Shampoo the hair then add the conditioner , put the hair in a plastic bag while the conditioner is on it then put it inside the microwave for 1min let it sit for at least two hrs I normally do overnight. It leaves the hair very soft and tangle free.
Seal your wefts to prevent shedding that may occur.
Never comb curly hair textures unless it is wet or contains conditioners and moisturizers. For our curly hair textures you will need a Spray Bottle, DENMAN Brush, and a WIDE tooth comb. You will also need Coconut Shea leave in conditioner by EDEN! It the bomb! During the summer or on while on vacation, you can wash your hair in the shower and lather the leave in conditioner while it's wet, SCRUNCH with a towel and then let it air dry. When you go to sleep at night first detangle your hair with a wide tooth comb. Next, braid your hair into 2-4 braids and wrap it up. In the morning, take the braids out, get a spray bottle and drench the hair in mixed water and leave in conditioner. Gently brush the hair with the Denman brush, scrunch, let let air dry and walaah!
Use a wide tooth comb to prevent hair ripping from the wefts.
Try not to put heat to your hair everyday, it can dry out your hair.
We recommend letting a professional color or process your hair extensions and using professional products for the best results (no cheap stuff). 
Never sleep with wet hair extensions. Always make sure the hair is dry and pulled up, or into a braid to keep hair from tangling at night.
