What texture works best with a spiral perm?

If you've got very fine hair that has trouble holding a curl, a spiral perm might not result in the bouncy ringlets you're looking for. Spiral perms seem to take best to hair that's more coarsely textured, or strands that already have some natural curls or waves in them. This means a spiral perm hairstyle is a popular choice for women with hair that’s got an irregular curl pattern. The spiral technique helps to create a uniform look that doesn't need to be touched up with heat styling tools.
