Blue Diamond Kollection strongly suggests that you wash your virgin hair with a good non-sulfate shampoo before installing your hair. We find Creme of Nature Ultra Moisturizing Shampoo works well.  DO NOT blow dry your wavy texture hair if you want to maintain the texture.  Allow the hair to air dry.   If you purchase deep wave, curly, or kinky curly hair, it is important to use a product that will keep your hair moisturized, as this texture can become dry.  NEVER use a tight comb on any texture hair, ONLY a wide tooth comb.  DO NOT use a comb or brush on your curly or kinky curly hair.  The deepwave hair can be flat ironed and curled.  To get the wavy texture back after straightening, simply wet the hair and allow to air dry.  You should treat your virgin hair as your own; meaning wash and condition it regularly, but never use shampoo or conditioner with sulfur.   Our hair can last two years or more with proper care.  

BE SURE TO WASH AND CONDITION YOUR BUNDLES AT A MINIMUM EVERY TWO WEEKS WITH A SHAMPOO AND CONDITIONER THAT DOES NOT CONTAIN SULFUR.  IF YOU PREFER, YOU CAN JUST COWASH YOUR BUNDLES WITH JUST CONDITIONER, BUT BE SURE TO RINSE THOROUGHLY SO THAT THE HAIR DOES NOT FEEL LIKE YOU HAVE LEFT PRODUCT ON IT.
