Cornrow, e.g.

BRAID

Think of a hairstyle where strands are intricately woven together, often seen in protective or cultural styles. It starts with "B" and is a common way to keep hair neat and tidy.

"Cornrow, e.g." is asking for a word that describes a type of hairstyle where hair is tightly woven close to the scalp, which is exactly what a braid can be. The clue uses "e.g." to signal that "cornrow" is just one example of this broader category. Since "braid" is the general term for interlaced strands of hair, it fits perfectly as the answer.
