This is 100% human hair suitable for braiding, without the weft. The hair can be curled or dyed, although it's advisable to purchase the hair in the color you want since the bundles are pre-dyed at the warehouse. This precaution helps maintain the integrity of the curl pattern, which might be altered if the hair is over-processed. Dyeing the hair more than two shades lighter is not recommended as it may change the curl texture.
