Is your hair curly or straight?

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.

What You’ll Need

How to conduct this experiment

THREEGLASSES

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: Once hair is dry, look at the circle on the screen. Roughly how much of your dry hair strand will fit inside the circle?

Results

If less than 1/2 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 3/4 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.
