Advanced Search Option: headshaving

I am specifically interested in stories that contain headshaving, yet there is no such search option yet. I am quite sure there are some stories in here that contain headshaving, but I have never been able to find any. I have tried search option combinations like "hair" + "modification" +"humiliation", but none brought me the desired result. I am quite sure that with so many members I am not the only one who is interested in that topic. Such an option would certainly be helpful.
