Our 3C Curly Hair Extensions are made to resemble 3c and 4a hair. The 3C curls are tight, corkscrew-like ringlets that are densely packed and have a lot of volume. 4a curls are packed in tight with a spiral pattern. If your natural hair has a similar curl pattern these extensions with blend perfectly! They are 100% human hair and require gentle handling and care to thrive. We recommend using products that are oil and alcohol free to avoid weighing the hair down or drying it out.
