Here is my blow dried hair (after I redyed it). I just blow dried it like I normally do, didn't do anything special to make it look worse or anything (I am terrible with using a roller brush so I just blow dry till like 75-80% of the wet is gone and then straighten it.)
And here it is after I styled it. It IS still red, even though it doesn't look like it. It didn't turn out like I had hoped. I used two different colored dyes on different parts of my hair, and you can see the colors in different lights, but oh well, it doesn't look too BAD.. At least it is softer, feels healthier and smells pretty good :P
