Crochet Braids by Benita Blocker using Caribbean Corkscrew Curl.
Caribbean Corkscrew Curl hair is easy to separate and grab. However, it can be quick to frizz.
Two of these packs go a long way.
I try to custom braid based on the desired final crochet braid style.
Crochet Braids by Benita Blocker using Freetress Water Wave hair. (full 4 packs)
I recommend highly textured braiding hair for those with silky natural hair or relaxed hair. I recommend silky braiding hair for those who have coarser natural hair. The coarser natural hair can have thick cornrows as a base and interlock silky braiding hair through both halves of the thick cornrows.
Silky braiding hair may match relaxed hair but it may slip out. That is why I recommend opposite textures of what you are working with. Thinner hair need more cornrows and some circular braiding patterns as a foundation.
If the braiding hair frizzes, then you can double strand twist in the areas that need taming. 2 to 5 packs should be plenty of braiding hair for one head.
The final cut of the crochet braids make it look most natural.
