Type 4a hair is tightly coiled hair that has a definite “S” curl pattern. The circumference of the spirals is close to that of a crochet needle, and hair can be wiry or fine-textured. It has more moisture than 4b, but is very fragile with lots of strands densely packed together. Type 4a hair also has fewer cuticle layers than other hair types, giving it less natural protection from damage.

Quick tip: Be sure to always keep creams, butters and oils on hand. They make the best stylers for type 4a hair.
