Explanation:
The two defining characteristics of hair type are wave patterns and hair texture.
Wave patterns refer to whether hair is straight, wavy, or curly. Straight hair has no noticeable wave, wavy hair has slight bends and curves, and curly hair has more defined and tight curls.
Hair texture, on the other hand, refers to the thickness or diameter of individual hair strands. It can be categorized as fine, medium, or coarse, depending on the width of the hair shaft.
