i have short, thick(lots of hairs), 3b hair. I am a CGer, and i love it. my problem is that my normally soft, tangle-free, manageable hair has suddenly become dryer and knotty. i haven't changed any of my products, or the way I take care of my hair, so why is my hair suddenly acting so different? if it makes any difference, i live in canada and it just got REALLY cold. is the cold drying out my hair? Please help! I want my nice hair back!
