Last time I was at the salon, my stylist told me I had splits. I monitor my hair very carefully and had not seen any splits. I seldom use heat.erplexed She showed me that the ends of my hair were a bit lighter in color than than the roots and that this was damage. But again, I could see no splits and the ends are thick and don't feel rough. Do I really need to trim or is this just normal weathering? I have not trimmed since February but am planning to trim when I next straighten my hair (August or September).
