Three things I would never do to my hair as a board certified dermatologist starting with number one sleep with wet hair. I would never go to bed at night after washing my hair, allowing my hair to stay wet and putting my precious head on a pillow only to wet the pillow to create the perfect breeding ground for moisture, yeast, fungus, you name it. Plus, when you're sleeping with wet hair, all that tugging and pulling, especially if you put it up in a bun or a ponytail, is going to cause more hair breakage. Number two Brushing your hair while it's wet. Now listen up it if you have fine hair and your hair is not textured or curly, you can allow your hair to air dry first before you brush it. But if you have textured or curly hair, your hair can be damp, not wet. Just make sure to use a wide tooth comb to break through those knots before going in with a wide brush.
