Straight to minimal wave

Comes in a variety of textures from thin (fine) to thick (coarse).
Hair grows down from the scalp.
Typically has trouble keeping curls in especily if it’s coarse.
Tends to lack body or volume.
It is less prone to frizz.
Open wave
Description: Open wave known as type 2a looks almost identical in appearance to type 1 but with barrel curls at the end.
It is defined by a loose big open wave.
It straightens easily using a warm temperature straightener or simply by brushing it straight.
Wavy / loose curls
Description: Type 2B, Distinct S-shaped curls with uniform wave pattern.
More tight then open wave and can be brushed straight aswell.
Some body volume or end curl and is less prone to frizz.
However, damaged type 2 hair can lose its waves and can end up with a type 1 frizzy appearance.

Type 3c hair maintains its curliness when wet and maintains a tight curl when dry.
