Frizzled is a term often used to describe hair that appears curly, wavy, or unruly. It can occur due to humidity, damage, or lack of moisture, leading to a frizzy texture that can be difficult to manage. People with naturally curly hair may experience frizz more frequently, especially in humid conditions. In the context of biology, Frizzled refers to a family of proteins that play a crucial role in cell signaling. These proteins are involved in the Wnt signaling pathway, which is important for various developmental processes and cellular functions. Frizzled proteins help transmit signals from outside the cell to the inside, influencing cell behavior and growth.
