2 questions for cosmeticians about hair styling products: wax/mud and root body spray?

Is there any difference between hair styling wax and hair molding mud for building body, definition %26amp; hold? If so, what is it? Is one not as effective as the other or are they for 2 different purposes? Also before my stylist blow dries my hair, she spritzes the roots with some sort of root spay that is supposed to add body. I was going to purchase some but someone told me that using plain old hair spray on damp hair has the same effect, is this true? Thanks if you can help.2 questions for cosmeticians about hair styling products: wax/mud and root body spray?
I AM not a beautician, but i do have tons of hair product. root lifter is the stuff she prays on your roots, and this will make your hair have more body. VO5 is really good, but the best is big sexy hair, also one of the best things to use on your hair is redkin rough paste, it comes in like a toothpaste pump, it's kind of thick, but it works great on short hair, it gives you the messy look. I put it on in the early morning, and at the end of the day , it still looks good. they are for two different purposes, the wax and molding, molding holds, and wax looks messy
