Type 4 is “kinky” or more appropriately full of tight coils (tightly curled hair). Typically, Type 4 hair is also extremely wiry and fragile.
4A: Your dense, springy coils are either wiry or fine, and have the circumference of a crochet needle. They are tightly coiled, with a visible S pattern.
4B: Instead of curling or coiling, your hair bends in sharp angles like the letter Z. The curl is tighter and less defined - about the circumference of a pen - with strands that range from fine and thin to wiry and coarse
4C: Your densely packed hair is similar to a 4b, but experiences less definition and more shrinkage. The tightly coiled strand texture ranges from super fine, thin and soft to wiry and coarse. It is very delicate.
