What is hair width, how do you measure it, and why does it matter?
One of the curl attributes that is often misunderstood and even left completely out of the curl conversation is hair width.
Fine strands have a small circumference and width and when held up to light appear thin and barely there. These strands tend to be weak and easily damaged.
Medium strands have a circumference between that of fine and coarse strands.
Coarse strands have the largest circumference and width and the most strength. When held up to the light the strands are very visible and when pulled on do not snap easily. Also it is important not to confuse the word coarse with the way hair feels.
