Straight hair lies flat on the scalp. As the hair’s natural oils are able to travel from the scalp to the ends, this type of hairs reflect the most sheen.

Wavy hair types form an “S” shape. It is thicker than straight hair types, and can be considered a medium between straight and curly hair. Because of its slight texture and shape, it is not as oily as straight hair.

Curly hair types are classified as spiral curls. Curly hairs form ringlets that are naturally defined and more prone to dryness, tangles, frizz and breakage. As the follicle does not lay flat, this hair type tends to be dry.
