Pennsylvania Esthetician State Board Practice Exam

Which type of hair growth refers to thick, coarse hair that forms a beard?

1. Lanugo

2. Cilia

3. Barb

4. Villus

The correct answer is: Barb

The type of hair growth that refers to thick, coarse hair forming a beard is commonly known as "barb" hair. In the context of hair types, barb hair is characterized by its density and coarseness, making it suitable for the facial and body hair that is typical in adult males. This type of hair is distinct from other types, which include lanugo, a fine and soft hair that typically covers the fetus; cilia, which are tiny hair-like structures mostly found on cells; and villus hair, which is fine, light hair found on most areas of the body. Understanding these different types of hair growth is important for estheticians, as it informs their approach to hair removal and related services.
