Which hair type is most prone to frizz?

1. Straight hair

2. Wavy hair

3. Curly hair

4. Coily hair

The correct answer is: Curly hair

Curly hair is most prone to frizz due to its unique structure and the way it interacts with moisture in the environment. Curly hair tends to have irregular shapes and bends, which can create more surface area for moisture to enter. When the humidity is high, the cuticles of curly hair can lift, allowing moisture to penetrate the hair shaft, leading to swelling and frizz. Additionally, curly hair often experiences more dryness because the natural oils produced by the scalp have a harder time traveling down the bends and loops of the hair strands. This lack of moisture balanced with environmental humidity can cause the hair to appear frizzy and undefined rather than smooth and sleek. Other hair types, such as straight and wavy hair, may experience frizz, but to a lesser extent. Straight hair typically lays flat, which can help maintain a smoother texture even in humid conditions. Wavy hair can have some frizz due to its uneven texture, but it is generally less prone to frizz than curly hair. Coily hair, similar to curly hair, can also experience frizz; however, its thick, tightly coiled structure can sometimes help it hold onto moisture better than looser curls.
