It does not have cool warm and hot. But, it does have low and high. Furthermore, this little dryer works well, and has the perfect temp. to blow dry your hair. And the best part is that the temp. leaves your hair shinny and alive. Unlike a blow dryer that gets to hot or cold and makes your hair frizzy, dry, unmanageable, and hard to style.
Sorry for leaving out these important details. And, thank you for bringing it to my attention. You are appreciated. Jacque B.
