I wore micros for a few months before I did the big chop anf continued to wear micros for a whole year. I got my micros done every three months but I would redo the hairline every 2 weeks. My main mmistake was not washing my hair and daily moisturising my braids which caused my to have brittle dry ends and two serious hair trims. But I feel the best things to do are daily cond washes (when possible) keep yaour ends tucked in as much as you can or wear twists, twistouts, and braids with consistent moisture applications.
