okay now that I see you have used it FL, I am interested in trying this Bigen out. How often can you re-apply it? I mean is it safe to re-apply in like a month or so after the last one? Anyone can shime in that can help with this. I want to be able to use it frequently if possible, say once every 3 weeks or so. If not, then I'll stick with indigo.
Thanks in advance.
