My first transition was for 9 mos (the length of my preg with my daughter). I BC'd (had about 4-5" and could barely squeeze it into a tiny tail) b/c I was just tired of seeing the relaxed hair, it wasn't necessarily hard to deal with. It grew out fast, and in 4 mos I had APL stretched.
This time, I plan to transition for as long as it takes...no BC just trimming a little here and there sparingly (not on a set schedule or set amount each time). If it takes more than 3 yrs for me to have at least MBL natural hair before all the texlaxed ends are gone, then thats fine. I don't ever plan to drastically cut my hair again. I'm in no rush, as this transition is a small part of a larger lifestyle change to more natural living practices for me. ☺ Oh yeah, I'm 7 mos, 1 wk into transition. 1 yr post July 22, 2010.
