This isn't much help but, I honestly don't know. The only reason/purpose I bought any kind of waffle knit towels was for drying my truck after the car wash. Never gave it any thought to use these for anything else. Sorry but hopefully someone else can be of more help.
This is a microfiber product. It is safe in contact with the skin. I suppose you could use it to dry your hair, but it's thin and not a bath towel. Excellent for pulling the water off a car, which is it's intended use.
