I'm not sure f every one is fimiliar with a bump. I apply sexy hair styling gunk, dry it a bot and tease my hair to make a bump without having a huge thing stuck in my hair. It works amazing for me and smells good too, that's always a plus :-)
I love everything Sexy Hair!!! I use a lot of their products. I have long curly hair and use this to keep my curls together and looking good. Love it! Highly recommended for short hair or curly. wavy longer hair.
