KEEP IN MIND:
Type 3A hair has loose spiral curls without a lot of shrinkage. The loop of your curl can fit around a large permanent marker. This hair type is usually not coarse to the touch, and its springs are bouncy and full of life.
Type 3B hair has tighter curls, with a spring back. A pencil can fit into your curls, which create fullness by bouncing off each other, plus they’re vulnerable to breakage and frizz.
Type 3C hair has curls like tight corkscrews with the circumference of a thin straw. These densely-packed curls create a lot of volume. Use a detangling comb from tip to root to help reduce damage.
Type 4A is prone to experience about 20% shrinkage as they tend to wrap around themselves.
Type 4B is also quite fragile and often has a high porosity, meaning it loses moisture very quickly. This hair type experiences about 50% shrinkage.
Type 4C experiences the greatest amount of shrinkage, about 75% or more than other textures.
