I have Black Diamond Wet an Wavy in my hair. I wanted to know if I coud straighten my hair with a sraightner, and then wHen I was tired of the straighten hair would it go back to the orignal type of being wavy/ curly when washed or moosed?? Is it a chance that it would not go back wavy?

Are you talking about chemically relaxing the hair or blow drying the hair straight? If you want to wear the hair straight you can do so by simply blow drying it straight and using a flat iron to bump the hair. Once you wash it and style it with moose or setting lotion the curls should bounce back, that is with any wavy quality hair. If you are not sure ask the beauty supply to provide you with a number to the sales director or the manufacturer they will be able to answer your questions with specific regard to the brand of hair.
