First thing is asking yourself how well hydrated do you keep your hair. I think a lot of newbies are trying to to get to curl def so fast they aren't focusing on enough on retaining moisture. The two are connected. Stylers to me are like icing on a cake and I don't think any styler is going to define parched hair. I believe moisture levels can build up over time in some hair and lead to more definition. If moisture is a problem and you have not already I suggest you try CG.
Yes, it's real. No, you can't touch it.
