Sunrise Bliss organic t-shirt towels are made with interlock knit cotton.  It is similar to jersey knit except both front and back are knit.  There are also additional threads running against the grain to give it more stability, which means it won't stretch out of shape or curl at the edges.   Interlock is the tightest knit and gives the smoothest surface.  

The fabric is very soft, firm and absorbent.  

Uses of this fabric include high-end t-shirts and baby layette items. If it's gentle enough for a baby, then it's gentle enough for your hair!
