I've put together some possible variations for Franklin's hairstyle.
Being that he's an aspiring hairstylist, I felt his hair needed somewhat of a flair, even if he is only a child.
Originally, a sort of unsettling bowl cut was in mind, although having explored some other options, I'm leaning towards options three and six.
Three has an unsettling hint of flair, whilst six is more in keeping with his age and neglected upbringing.
The final hairstyle will probably fall into place when the rest of his appearance is refined.
