1. Girls with Curls
The Origins of Curl Patterns and
Textures around the World

2. What do we know
about curls?
More often than not we’re
born with hair similar to that
of a family member’s.
However, the texture of our
hair may change over time for
specific reasons.
Learn what causes those
curls, and determine what
classification of hair you
have.

3. The Role of Genetics
Born Wild
Scientists have identified
specific genes that determine
if your hair will be curly,
straight, or somewhere in-
between. This sort of
variance is referred to as a
“continuous trait.”
Baby, those soft curls are
nature-made.

4. Travel Back to Your Roots
The Origins of CurlsVariance within a
multitude of genes is
apparent when looking
at hair textures around
the world.
For example, while curly hair is
prominent among people of black
African descent, it is rarely seen
among Asian populations.
These gene variations also explain
the diverse textures of hair across
Europe.

5. The Role of Hormones
Stages of Life
Women go through several bodily
changes throughout a life time due
to hormones – and the texture of
your hair is one change most
women readily noticed.
Puberty, pregnancy, and
menopause are “the big three” in
terms of making a curly-haired girl
go straight, and vice versa.

6. Hair Classification
Systems
There are many systems
used to classify hair types
and textures.
3 Popular Methods
include:
+ Andre Walker Hair
Typing System

two visible S-waves
The Wavy Ones

throughout the hair
2b. Shorter, more distinct S-waves
