The texture changes I've noticed arent due to growth specifically, but the hair growing out being healthy and undamaged. When I first transitioned I was using heat to blend my ng and relaxed hair, so I had some heat damage, and then I was using some holders that were too rough for my hair. As it got long enough to pull back and protect from damage, and I was more careful rubbing up against pillows etc, the strands appear smoother, because they arent broken and split. I still have some damage, but most of it has been cut off. As my hair gets longer and heavier, it does "hang" better. Products with some weight help also.
