In Andre Walker’s hair typology, each “hair type” has two components: curl type and strand thickness. Curl type is designated with a number, and strand thickness is designated with a letter.

The curl type can be any number 1-4. Here is what they are:

  1. Straight
  2. Wavy
  3. Curly
  4. Kinky, Zig-zag (“Afro-textured”)

Brambleroots typically gives information based on the broad categories of the curl types listed above. But in case you’re curious, the hair texture letters are as follows:

  1. Fine (thin)
  2. Medium
  3. Coarse (thick)

Type “3c” tends to be the only exception to this rule; basically, it is “telephone cord”-like ringlets. This is usually found only in mixed-race and black hair.

For supplementary information, check out this site. Though the images are rather vague, the site has a great text table that explains each letter and number combination.

A given hair type does not suggest anything good or bad about one’s hair. It is not a categorization system used to discriminate; it is used on this site to match each hair type with the best starting and maintenance methods.
