Nothing is worse than drying your face with a scratchy towel. End this dilemma by adding 1/2 cup of apple cider vinegar to your usual wash load during the rinse cycle (use only 1/4 cup, in the bleach compartment, for high efficiency washers). The acetic acid in the vinegar breaks down the detergent buildup and relaxes the fibers to soften without any irritation to your skin.
