WAVY TO CURLY HAIR - TYPE 2
Wavy to curly hair takes on an S shape or winds around a spiral shape. Because the natural shape can easily be weighed down by heavy products, wavy to curly hair needs lightweight conditioner and defining care. Its loose curl shape does allow natural oils to travel down the shaft, so only a medium amount of extra moisture and nutrition is necessary.
VERY CURLY HAIR - TYPE 3
Very curly hair can come in the form of loose curls or tight, springy corkscrew curls with strands winding closely around themselves. The fiber tends to be more porous and fragile than wavy to curly hair. At the same time, because of the tighter curl shape, it’s more challenging for natural moisture to reach the ends, so very curly hair needs intense hydration and strengthening products such as a hair mask and layered-on leave-in treatments.
COILY HAIR - TYPE 4
Coily hair can come in tight corkscrews, or a zig-zag pattern. The curls are very dense near the scalp and loosen a bit toward the ends. The fiber is thinner and more fragile, with a higher risk of breakage. Because natural oils have a hard time traveling down the shaft, it is also extremely dry. Coily hair requires maximum nutrition, strength and definition that can be achieved with lots of layered products and intense treatment oils that can be left on overnight.
