Is Your Hair Curly Or Straight?

A Simple Test to Learn More About Your Hair


What This Is Testing:

Hair Curvature

Why This Is Important:

When you have very curly hair, the hair strands’ twists and turns require special care.


How to Conduct This Experiment:

  • Step 1: Take a hair strand from the middle to back of your head (approximately 6 inches in length).

  • Step 2: Wet the hair strand with water, and then let it dry naturally.

  • Step 3: After the hair is dry, look at the circle on the screen. Determine, roughly, how much of your dry hair strand will fit inside the circle.


  • Results

    If less than one half of the hair strand is within the circle, your hair is mostly straight and needs conditioning that helps to align and protect hair from damage.


    If at least three-fourths of the hair strand is within the circle, your hair is mostly curly and needs moisturizers that help seal and smooth cuticle edges, define curls, and control frizz.
