I cut about half inch off because my ends were making me cringe.
What I did was roller set into about 8 big pieces. As I detangled each piece, I took about 1/2 inch off before I set it. I have 4 weeks to make it up so hopefully this doesn't hurt my progress. I need way more than 1/2 inch to make it to APL anyhow. No sense growing roots and getting length when my ends keep breaking or look suspect so it needed to be done. Now I won't be tempted for the rest of the year. I will admit I already dusted at my last relaxer but I felt this was necessary because the ends looked so horrible.
