Curly hair is “S” shaped and ranges from loose, bouncy curls to springy, tight corkscrew curls. They are often well defined and bouncy which can lead to a lot of body, but they can be easily styled in their natural state or straightened with a blow dryer. Curly (Fine) Hair and Curly (Thick) Hair are distinctly different ... but not in the way you may think! To determine whether your Curly hair is Fine or Thick, you want to look at individual strand thickness and not overall hair density.
