What is the difference between glycerin and vegetable glycerin. I bought [buylink=http://www.curlmart.com/Jessicurl-Awe-Inspiraling-Spray-p-102.html?utm_source=naturallycurly.com&utm_medium=text-link&utm_content=curltalk-post-text&utm_campaign=jessicurl-awe-inspiraling-spray]Jessicurl Awe Inspiraling spray[/buylink] and just assumed it had all the right stuff for my hair. I checked the ingredients after I received it and it has vegetable glycerin! My hair doesn't like glycerin! Does anyone know the difference between them if there is any? Thanks.
