Big hair

I think you are supposed to like pick up a section of hair and comb the side you can't see from the front from the ends to the roots. I think you can use a brush or a comb. I think you spray the top like after you smooth it. I've never done it because it's bad for your hair and my hair is already naturally huge. But I don't think you are supposed to tease the very front section of hair or your hair will look messy. Here I found an article on backcombing.

Then pull up undersections and run the comb back from the ends to the roots, catching some of the hair and pushing it back. This will make teased sections, which will look fluffy. When you are done, smooth over the top and spray into place.

I don`t understand your instructions...but can you translate it into something I can understand for hair dummies?
I appreciate your reply.
