How do I know if I have 2B hair?

Air-dried, your hair forms clear S-shaped waves starting closer to the root than 2A, and the crown tends to frizz while the ends hold their shape. The waves have real definition but no spiral or ringlet.

Key characteristics of 2B hair

Medium strand diameter with a defined S-pattern
Waves begin closer to the root than 2A
The crown is noticeably frizz-prone
Holds a wave pattern reasonably well once styled
Responds well to the Curly Girl Method

The one thing 2B hair struggles with most

Frizz at the crown while the ends stay defined. Type 2B has enough pattern to hold a shape but the shorter, finer strands at the crown escape it, which is why the top looks fuzzy while the bottom looks good.

2B hair and porosity

2B hair spans the full porosity range. If your waves go crunchy and straw-like with protein-containing products, you are likely protein-sensitive and should choose protein-free conditioners.
