Congrats to you on your mini chop!! I know what you mean about being nervous cutting off your hair and getting closer to being all natural. My last relaxer was 11/02/11 and I will cut all my relaxed ends on my 1 year relaxer-free anniversary this November.
I have been doing mini chops since I reached 7 months post. I trim 1/2 an inch off, and I plan to do so each month until November. The crazy thing is, as much as I don't want to cut a lot of my hair off (I eventually will), this method has been making my hair seem like it is growing like crazy!! And the beautiful part is seeing more and more of my natural texture shining through!!
Your hair looks so healthy, and your natural texture is also beautiful. Good luck on the rest of your journey.
